Token introduced the semishielded inductor series using magnetic epoxy resin as a magnetic shield. As its name suggests, the semishielded inductor is design to bridge the performance gap of shielded and nonshielded inductors by offering users an additional selection of inductor series.
To take the advantage of a shielded inductor is its low radiation which can be characterized from its lowest coupling factor among other type of inductors. Whereas the magnetic flux of its nonshielded counterpart is not confined to a given vicinity. These inductors experience the highest coupling factor.
Token Electronics has added those new generation portable products in new ranges of highcurrent chip inductors, TPSTP2110, TPSTP2112, TPSTP2114, and TPSTP2816, for use in DCDC converter applications to increase flexibility of maximum height measurements with extended electrical characteristics.
The new ranges deliver a good size/performance ratio with compact packaging size is designed to save space, measuring 21mm x 14.5mm (TPSTP). A wide range of inductances is also available: 0.3μH to 33μH. The parts come with high rated currents, up to 35A, and feature magnetic shielding as standard. Operating temperature range is 55°C to +125°C.
Custom parts are available on request. Token will also produce devices outside these specifications to meet specific customer requirements, please contact our sales for more information.
