How to Request Samples

Even in this economy, an honest and polite letter requesting samples goes a long way. Most electronics components manufacturers provide samples for free, or for the cost of shipping and handling. Don't feel bad if they decline, but if you don't ask, it will not happen at all. And most important, if you or people you might know (e.g. next year's team) need samples from them in the future, make sure you send a Thank You Letter!

The following are Request and Thank You letter examples. You can probably do better!


  • Be as specific as possible to make it as easy as possible for the company rep to place the sample order for you. Try to have complete part numbers, catalog numbers, and correct description.
  • Don't forget the Quantity you need. Keep it low, but allow for mistakes.
  • Check retailers like Digikey to see if the parts are in stock, if not, provide alternative part numbers that comply with your needs.
