Passive components do not require energy to operate and include diodes, capacitors, resistors, transformers, and other basic circuit elements. Several manufacturers provide samples of these components, though availability varies by company and specific product lines.

Connectors

Connectors serve as critical interfaces between different electronic components and systems. Various manufacturers offer free samples of different connector types to help engineers test compatibility and performance in their specific applications.

Fuses and Protection Devices

Components like fuses and gas tubes are vital for circuit protection. Manufacturers such as Little Fuse provide free samples of these protection devices without requiring registration, allowing users to test their effectiveness in various applications.

RF Components

Radio frequency (RF) components are specialized parts designed for high-frequency applications. Mini-Circuits offers an extensive selection of their surface mount RF components for free sampling through their EZ Sample program, supporting product validation efforts across various industries.

How to Request Electronic Component Samples

The process for obtaining electronic samples follows a general pattern, though specific requirements vary by manufacturer:

Registration and Account Creation

Many manufacturers require users to create an account on their website before requesting samples. This typically involves providing basic contact information and sometimes details about professional background or intended use. Some companies, like Little Fuse, do not require registration at all.

Locating Sample Request Forms

Manufacturers typically have dedicated sections for sample requests on their websites. Sample request buttons can sometimes be difficult to locate, as noted by several sources. If unable to find the appropriate form, direct email contact with the manufacturer is recommended.

Selecting Components

Once registered, users can browse through available components and select specific parts for sampling. Some manufacturers impose limitations on the number of samples that can be requested within a specific timeframe, such as Mini-Circuits' policy of maximum 5 samples within any 30-day period.

Providing Project Information

Manufacturers commonly request information about the intended use for the samples to ensure they are used appropriately. This may include details about the application, industry, or specific project goals.

Submitting the Request

After completing all required information, users submit their sample request. Some manufacturers provide immediate confirmation, while others may review the request before approval.

Processing and Shipping

Approved samples are processed and shipped according to the manufacturer's policies. Shipping methods and times vary, with some offering expedited options like FedEx 2nd Day Air or UPS 2nd Day Air at no additional cost to the requester.

Manufacturers Offering Free Electronic Samples

Zilog

Zilog provides free samples of semiconductors and microcontrollers. The company requires registration through a sample request form but does not mandate a corporate email address. Once approved, samples are shipped via FedEx 2nd Day Air without any shipping charges to the requester.

Little Fuse

Little Fuse offers free samples of fuses, gas tubes, and other protection devices. Unlike many other manufacturers, Little Fuse does not require registration for sample requests. Approved samples are shipped via UPS 2nd Day Air without any shipping costs.

Manufacturers That Do Not Offer Free Samples

Several manufacturers that initially appeared to offer samples did not fulfill requests according to user reports:

Vishay

Vishay, which produces passive components, requires registration but reportedly did not provide free samples to requesters. This suggests that registration alone does not guarantee sample availability.

Wima

Wima, a capacitor manufacturer, provides a sample request form but reportedly refused to send free samples to requesters, despite having a formal process in place.

AVX

AVX offers a sample request form for passive components and does not require registration, but reportedly did not provide free samples to those who submitted requests.

Delevan

Delevan, which produces transformers and inductors, does not have a sample request form. Users must contact a sales representative via email, but the company reportedly did not provide free samples.

MCI Transformer

Similar to Delevan, MCI Transformer does not have a sample request form and requires email contact with a sales representative. The company reportedly did not provide free samples to requesters.

Alternative Sources for Electronic Components

Surplus Websites and Suppliers

While not offering free samples, some suppliers provide components at competitive prices. Digi-Key is recommended as a supplier with a huge selection of electronic parts at fairly good prices, though they do not offer free samples. These suppliers can be a cost-effective alternative when sample programs are not available.

Free Used Disposable Cameras

An unconventional source for electronic components is free used disposable cameras, which can be obtained from stores with photo departments such as Walmart, CVS, and Walgreens. These cameras contain electronic components that can be useful for various projects, particularly for those just starting in electronics.

International Suppliers

Some international suppliers offer components with free shipping: - Maplin: A UK-based supplier with physical stores and an online store. While components are standard internationally, international shipping might be a consideration for US-based customers. - DealExtreme: A China-based website with US pricing that offers free shipping on all items, including electronic components and project materials. This can be particularly advantageous for small electronic parts and project materials.

Rules and Ethical Considerations When Requesting Free Samples

When obtaining free electronic samples, it's important to follow certain guidelines and ethical practices:

Be Reasonable in Requests

Only request the number of samples you actually need for your projects. As noted in the source materials, "You should never ask for more than you need, because you are not going to use the extra parts you are given, that means don't be greedy." Excessive requests can deplete available samples for others and may result in restrictions on future access.

Do Not Resell Samples

Free samples are intended for personal projects and evaluation purposes. Selling samples obtained for free on platforms like eBay is explicitly prohibited unless explicitly permitted by the manufacturer. The source materials emphasize that "Taking free samples from the companies and selling them on places like ebay to make your self an profit is an absolute no-no (unless the company says you can do it)."

Support Companies When Possible

Consider purchasing products from companies that provide free samples, especially if you find their components useful in your projects. As suggested in the source materials, "Just to be fair to the companies where you got your samples from, buy some of their products." This helps support the companies that provide samples and encourages them to continue offering these programs.

Provide Accurate Information

When requesting samples, provide truthful information about your intended use and project details. Misrepresenting your purpose may result in losing access to sample programs and potentially damaging relationships with suppliers.

Check for Sample Request Buttons

Some manufacturers have sample request buttons that can be difficult to locate on their websites. As noted in the source materials, "Also look for the sample buttons because they are hard to spot sometimes but if you can't then you should send an E-mail!" Persistence in finding the proper request method is important.

Stay Updated on Program Changes

Sample programs and availability can change over time. Checking back periodically for updates on which companies offer samples and any changes to their policies is recommended. Some sources indicate that sample programs are regularly updated, so staying informed is beneficial.

Conclusion

Free electronic samples provide valuable opportunities for engineers, hobbyists, and students to test components before purchasing. While not all manufacturers offer samples, several companies like Zilog, Little Fuse, and Mini-Circuits provide free samples of their products through structured programs. Services like Beganto's Need-A-Sample offer access to samples from multiple suppliers, though they require membership. When requesting samples, it's important to follow ethical guidelines, be reasonable in requests, and respect the terms set by manufacturers. By adhering to these practices, individuals can benefit from sample programs while maintaining positive relationships with component suppliers.
