Gowanda ER3013 inductors offer ER SMT for military RF

Believed to be the first in the industry, the Gowanda ER3013 inductors are the first off-the-shelf RF (radio frequency) surface mount (SMT) inductors with established reliability (ER) rating.

The Gowanda ER3013 is designed for military RF applications. The series was developed by Gowanda in response to a market need for surface mount options to the traditional leaded (through-hole) designs.

Surface mount configurations lend themselves to higher-efficiency pick-and-place circuit board assembly processes, rather than the more laborious, multi-step throu-gh hole assembly methods. The introduction of the ER SMT series will enable faster assembly processing, promises Gowanda, helping to reduce the cost of high-reliability electronic systems where ER components are used. The introduction of this new series also reassures the design community that SMT designs are attainable even for some of the most challenging high-reliability components.

The development from Gowanda not only breaks new ground but also helps to assure design engineers that their next generation designs will have access to the necessary components. Gowanda plans to introduce more ER SMT designs in the future.

The ER3013 series meets the military’s Qualified Products List (QPL) requirements for ER to failure rate level M and addresses three MIL-PRF-39010 slash numbers (/19, /20 and /21). This qualification requires 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. 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, moulded ER3013 series is designed for RF applications in military, aerospace and space – including defence and NASA communities – for use in communication, guidance, security, radar, test and evaluation and special mission applications.

          

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