Shielded Surface Mount RF Inductors With Higher Inductance

19 February 2018

Gowanda Electronics, a designer and manufacturer of precision electronic components for radio frequency and power applications, announces the expansion of its SML32S series of wirewound, shielded, molded RF surface mount inductors in the “1210” style. This expansion increases the number of individual parts in the series by more than 20 percent and broadens the inductance range by adding values from 120 to 470 microhenries (uH).

The expansion addresses the market need for higher inductance shielded inductors in RF applications. Shielded Source: Gowanda ElectronicsSource: Gowanda Electronicsinductors are 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. Such inductors are used for radio frequency applications in commercial, medical and military communities, including communication, guidance, security, radar, and test and evaluation applications.

The performance range provided by the expanded SML32S series includes inductance from 0.1 uH to 470 uH, DCR ohms max from 0.15 to 25 and current rating of milliamperes of direct current from 91 to 1,175. There are two core types in the series (powdered iron or ferrite). The series operating temperature range is minus 55 degrees Celsius to 125 degrees Celsius.

The SML32S series is the magnetically shielded version of Gowanda’s SML32 series. Both SML32S and SML32 series are part of the company’s Standard RF Surface Mount Inductors product line.
