Higher Rating Achieved on RF Inductors for Military Market

Gowanda Electronics, a designer and manufacturer of precision electronic components for radio frequency and power applications, announced achievement of failure rate Level R on two more of its MIL-PRF-39010 RF Inductor Series – ER15M and ER18M – adding to the company’s series already approved to Level R – ER10M and ER17S. These four thru-hole series meet the military’s Qualified Product List (QPL) requirements for Established Reliability (ER) and address ten different MIL-PRF-39010 slash numbers (/01 through /10). This approval required extensive testing for electrical, environmental, mechanical and thermal performance. Level R represents the most reliable off-the-shelf inductors for high-reliability applications.

Gowanda’s “ER” series are designed for RF applications in military, aerospace and space – including defense and NASA communities. This includes use in communication, guidance and security applications, as well as in radar, test & evaluation, and special mission applications.

These four ER series were initially introduced with Level M approval. As part of the company’s commitment to the military market, Gowanda pursued the testing required to attain higher level approvals – first achieving Level P – and now Level R – on all four series. Level R represents a 100X increase in reliability over the initial Level M rating. Gowanda’s four series have cumulatively exceeded 45 million unit hours of testing.

The overall performance range provided by the four series includes inductance from 0.10 to 1000 uH, Q min from 25 to 75, SRF MHz min from 3.4 to 680, DCR Ohms max from 0.025 to 72, and current rating mA DC from 28 to 2900.
