The TPSRB series of wire wound, surface-mount inductor from Token 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 5.90 mm x 6.50 mm x 3.50 mm for TPSR63B, 7.35 mm x 8.15 mm x 4.90 mm for TPSR74B, 9.40 mm x 10.40 mm x 5.50 mm for TPSR105B. The inductors are magnetically shielded to prevent interference and operate in a temperature range of -40C to +85C. Token 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.
