Important QPL Update

It has come to our attention that there are several errors at the US Defense Logistics Agency website, specifically the omission of Gowanda Electronics from the QPL listing for several MIL-PRF-83446 slash numbers. The DLA is taking steps to fix these errors at their website. In the meantime please refer to the original DLA qualification letters for correct information.

Gowanda is a leader in the design and production of robust inductors for the military/aerospace, space and defense industries. The company’s success is derived from decades of magnetics expertise, focused attention on the technical requirements of such demanding applications and collaborative relationships with customers’ design engineering teams. Numerous inductor series have achieved Qualified Product List status as a result of Gowanda’s commitment to the process controls, testing and investment required. The company has led the industry with several ‘firsts’ as well.

  • MIL-PRF-83446 – first with 0603 & 0805 chip inductors
  • MIL-PRF-27 – first with Level T
  • MIL-PRF-39010 – first with SMT ER & ER Shielded

OVERVIEW

Military and High Rel Applications

Our current Qualified Product List designs include RF and power inductors which meet the demanding requirements of military and high reliability applications where reliable performance is a necessity, not an option. We are committed to expanding our QPL product line for the global marketplace in response to increasing demand for qualified inductors. QPL products are used in communication applications such as space, satellite, radio, sonar, GPS and guidance, as well as in radar, test & evaluation, security and special mission applications.
