Gowanda: Higher Rating on MIL RF Inductors
RF inductors approved to Level P for MIL-PRF-39010.
Gowanda, NY — Gowanda Electronics has recently achieved failure rate Level P for its MIL-PRF-39010 RF Inductors — ER10M Series and ER17S Series. These thru-hole series meet the military's Qualified Product List (QPL) requirements for Established Reliability (ER). Such approval requires extensive life testing of electrical, environmental, mechanical and thermal performance.

The company's ER10M and ER17S Series were introduced in the fall of 2010 with Level M approval and represented the company's first ER products for the military market. As a result of a commitment to do the required testing to achieve higher level approvals, the ER10M and ER17S inductors now meet the relevant MIL-PRF-39010 specifications to failure rate Level P. The company is continuing to do life testing at its in-house environmental testing lab with a goal of attaining the more demanding failure rate — Level R.

ER10M is a wirewound, molded design approved for MIL-PRF-39010/08, /09 and /10. Performance includes: inductance from 0.10 to 1000µH; Q Min from 25 to 55; SRF from 3.4MHz Min to 680MHz; DCR from 0.08 to 72Ω Max and DC current rating from 28 to 1350mA. Operating temperature is -55 to +125°C for /08 and -55 to +105°C for /09 and /10.

ER17S is a wirewound, molded, shielded design approved for MIL-PRF-39010/01, /02 and /03. Performance includes: inductance from 0.10 to 1000µH; Q Min from 40 to 60; SRF from 3.8 to 250MHz; DCR from 0.025 to 17.5Ω Max and DC current rating from 70 to 1790mA. Operating temperature is -55 to +105°C.

These new RF inductors reportedly represent the most reliable off-the-shelf inductors offered in the industry for high-reliability applications. They also demonstrate the company's ongoing commitment to the development and introduction of QPL products which address the needs of the military and aerospace markets.

The new inductors are designed for RF applications in military, aerospace and defense communities. This includes use in communications, guidance and security applications, as well as in radar, test and evaluation, and special mission applications.
