These Established Reliability series meet MIL-PRF-39010 Level R for high-rel applications. Level R represents a 100X increase in reliability over the initial Level M rating. Gowanda’s four ER series are designed for radio frequency applications in military, aerospace and space.
Gowanda Electronics, a designer and manufacturer of precision electronic components for radio frequency and power applications, announces achievement of failure rating 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 (shielded). 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.
The overall performance ranges provided by the four series include inductance from 0.10 to 1000 µH, 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. Series-specific values are provided in the table below.
The MIL-PRF-39010 slash number also 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).
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.
Testing was performed at Gowanda’s in-house environmental lab. This lab is Defense Logistics Agency Land and Maritime approved (in support of internal product qualifications).
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.
