Gowanda is First in Industry to Offer Shielded ER SMT Inductors for Military RF Applications
“This introduction of a shielded ER surface mount series is a result of Gowanda’s commitment to develop inductor designs that address the evolving needs of the design engineering community,” said Don McElheny, CEO of Gowanda Components Group. “We will continue to introduce more ER SMT series in the future”, he added.
The ER5025S series meets the military’s QPL requirements for Established Reliability to failure rate level M and addresses two MIL-PRF-39010 slash numbers (/17 and /18). 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 shielded ER SMT series.
Gowanda’s wirewound, molded, shielded ER5025S series is 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. This shielded series – with 3% max coupling – is used specifically in applications where the close proximity of circuit board components requires the inductor to be shielded to minimize interactions and ensure performance of the overall system.
The performance range provided by the ER5025S series includes inductance from 0.10 to 10,000 µH, Q min from 40 to 60, SRF MHz min from 1.0 to 450, DCR Ohms max from 0.025 to 139, and current rating mA DC from 30 to 2245. The MIL-PRF-39010 slash number determines specific performance, core type (phenolic, powdered iron or ferrite) and shielding type (iron sleeve or ferrite sleeve). Operating temperature range is -55°C to +105°C.

Gowanda has been designing and manufacturing RF and power inductors – both thru-hole and SMT – for the military’s Qualified Products List for many years. That experience combined with several successful ER thru-hole qualifications set the stage for the development of the industry’s first ER SMT inductors last year, and now the industry’s first shielded ER SMT inductors.
