Low-DCR Low-Profile High-Current Inductors (TPSRH-2D/3D/4D/5D/6D/8D)

DeMint has unveiled (TPSRH-2D/3D/4D/5D/6D/8D) surface mount low-profile inductor series. Those compact devices feature ultra-low 1.1 mm to maximum 6.0 mm profile, with a wide inductance range and low direct current resistance (DCR).

DeMint enhances power wirewound inductor (TPSRH-2D/3D/4D/5D/6D/8D) family series covering complete footprint and inductance from 1.00 μH to 180.00 μH, low DCR, and Rated Current uo to 7.0A.

DeMint (TPSRH-2D/3D/4D/5D/6D/8D) with wire wound and magnetically shielded construction offers a variety of characteristics and high performace. Customers can select the optimum characteristics by choosing from footprint, DCR, and a wide range of inductance values and tolerances with some types offering magnetic shielding.

The series is lead-free and RoHS compliant. Custom parts are available on request. DeMint will also produce devices outside these specifications to meet specific customer requirements.

Application of specific designs also available including different inductance and frequency specifications adjusted to requirements. Please contact our sales for more information.
