First in Industry - Shielded RF SMT Inductors with Established Reliability
Gowanda's ER5025S provides MIL-PRF-39010 qualified inductors in surface mount configuration for military and other high reliability RF applications.
Gowanda Electronics, a designer and manufacturer of precision electronic components for radio frequency and power applications, announces the introduction of the industry’s first off-the-shelf Shielded RF Surface Mount (SMT) Inductors with Established Reliability (ER) rating. The first-ever shielded ER SMT series – Gowanda ER5025S – complements MIL-PRF-39010 Qualified Product List (QPL) axial-leaded (thru-hole) products and enables their conversion to SMT circuitry via this new MIL-PRF-39010 qualified SMT series. This series was developed by the company in response to a market need for shielded surface mount options to the traditional thru-hole designs. SMT components enable the use of more efficient assembly methods when compared to thru-hole methods. Gowanda was the first in the industry to offer an ER series in a surface mount configuration last year, Gowanda ER3013.
“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. See the
performance data table and ER5025S datasheet link below for additional
information.
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. Gowanda’s new Hi-Rel QPL Brochure provides a helpful
overview.
