Shielded surface mount RF inductors with higher inductance

Gowanda Electronics has announced 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% and broadens the inductance range by adding values from 120 µH to 470 µH. The expansion was done in order to address the market need for higher inductance shielded inductors in RF applications.

Shielded inductors are used specifically in applications where the close proximity of circuit board components requires the inductor to be shielded to minimise interactions and ensure performance of the overall system.

Such inductors are used for radio frequency applications in commercial, medical and military communities. That includes use in communication, guidance, security, radar, and test & evaluation applications. 

The performance range provided by the expanded SML32S series includes inductance from 0.1 µH to 470 µH, DCR ohms max from 0.15 to 25 and current rating mA DC from 91 to 1175. There are two core types in the series (powdered iron and ferrite).

The series operating temperature range is -55°C to +125°C. See data table below. More technical information is available on the SML32S datasheet, series page and graphs page (links below). The SML32S series is the magnetically shielded version of Gowanda’s SML32 series.
