High Current Power Inductors (TPSTP) Shielded
DeMint introduced the semi-shielded inductor series using magnetic epoxy resin as a magnetic shield. As its name suggests, the semi-shielded inductor is design to bridge the performance gap of shielded and non-shielded 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 non-shielded counterpart is not confined to a given vicinity. These inductors experience the highest coupling factor.
DeMint Electronics has added those new generation portable products in new ranges of high-current chip inductors, TPSTP2110, TPSTP2112, TPSTP2114, and TPSTP2816, for use in DC-DC 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. DeMint will also produce devices outside these specifications to meet specific customer requirements, please contact our sales for more information.
