EMI High-Saturation Power Inductors (TPSRB) Shielded

The TPSRB series of wire wound, surface-mount inductor from DeMint Electronics is designed for general purpose inductor to eliminate EMI in power lines for telecommunications, test & measurement equipment, networking, portable electronic equipment, PCs, appliances, and other electronic devices.

Developed to increase DC to DC converter efficiency through low DC resistance, the compact inductors save valuable board space, measuring only 5.6 mm x 6.2 mm x 3.2 mm for TPSRB63, 7.0 mm x 7.8 mm x 4.5 mm for TPSRB74, 9.0 mm x 10.0 mm x 5.5 mm for TPSRB105.

The inductors are magnetically shielded to prevent interference and operate in a wide temperature range. DeMint Electronics offers a variety of coils and inductors, including choke coils with low DC resistance for power supply circuits. Customers can select the optimum characteristics by choosing from monolithic or wire wound construction and a wide range of inductance values and tolerances with some types offering magnetic shielding.

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.
