Gowanda Electronics has revealed that it was able to achieve failure rate Level R on two more of its MIL-PRF-39010 RF inductor series, ER15M and ER18M, adding to its previously approved to Level R, ER10M and ER17S. According to the company, the 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 is geared for RF applications in military, aerospace and space including defence and NASA communities. This includes use in communication, guidance and security applications, as well as in radar, test and evaluation, and special mission applications.

ER series

These four ER series were initially introduced with Level M approval. 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 0.10uH to 1000uH, 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, detailed the company.

The MIL-PRF-39010 slash number determines the core type (phenolic, powdered iron or ferrite), shielding (iron sleeve or ferrite sleeve), and operating temperature range (-55°C to 105°C or -55°C to 125°C).
