World's First RF Surface Mount Inductors with Established Reliability Rating

Gowanda Electronics has introducted the first off-the-shelf RF Surface Mount (SMT) Inductors with an Established Reliability (ER) rating. The ER SMT series of inductors were developed by Gowanda in response to a market need for surface mount options to the traditional leaded (thru-hole) designs.

The Surface mount configurations lend themselves to higher-efficiency “pick and place” circuit board assembly processes versus the more laborious, multi-step thru-hole assembly methods. The introduction of the ER SMT series will enable faster assembly processing, thereby helping to reduce the cost of high-reliability electronic systems where ER components are utilized.

The ER3013 series meets the military’s Qualified Products List (QPL) requirements for Established Reliability to failure rate level M and addresses MIL-PRF-39010 slash numbers /19, /20 and /21. This qualification required extensive testing for electrical, environmental, mechanical and thermal performance. Level M represents the first level of failure rating for off-the-shelf inductors for high-reliability applications. In its ongoing commitment to the military market, Gowanda intends to achieve higher level failure ratings (Level P, then Level R) as ongoing testing continues to accumulate the hours necessary to attain those ratings on this ER SMT series.

Gowanda’s wirewound, molded ER3013 series has been designed for RF applications in military, aerospace and space, including defense and NASA communities for use in communication, guidance, security, radar, test & evaluation and special mission applications.

The performance range provided by the ER3013 series includes inductance values from 0.10 to 1000 µH, Q from 25 to 55, SRF from 3.4 to 680 MHz, DCR Ohms max from 0.08 to 72, and current rating mA DC from 28 to 1380. The specific MIL-PRF-39010 slash number determines the core type (phenolic, powdered iron or ferrite) and operating temperature range (-55°C to +105°C or -55°C to +125°C).
