Higher Rating for Gowanda MIL Inductors
Encapsulated military inductors get rating boost.
Gowanda, NY — Gowanda Electronics has recently achieved failure rate Level R for its MIL-PRF-39010 RF Inductors — ER10M Series and ER17S Series. These thru-hole inductors meet the military's Qualified Product List (QPL) requirements for Established Reliability (ER). Such approval requires extensive testing for electrical, environmental, mechanical and thermal performance. Level R represents a 10X increase in reliability over the prior Level P rating for these two series. Each series has exceeded 10 million unit hours of life testing to date.

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 reached level P in April 2011 and now meet the relevant MIL-PRF-39010 specifications to 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 MHz Min from 3.4 to 680; DCR Ohms Max from 0.08 to 72 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 Min from 3.8 to 250MHz; DCR Ohms Max from 0.025 to 17.5 and Current Rating DC mA from 70 to 1790. Operating Temperature is -55 to +105°C.

These Level R series represent the most reliable off-the-shelf inductors offered 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 ER10M and ER17S series are designed for RF applications in military, aerospace and defense communities. This includes use in communication, guidance and security applications, as well as in radar, test and evaluation, and special mission applications.
