Token introduces surface mount lower DCR Shielded Power Inductors. To meet the electrical demands of next-generation products such as microprocessors, high-current dc/dc converters and telecom equipment, the (TPSDC) SMD Inductors from Token Electronic targets applications that require wide range inductance, lower DCR and high current.

Token TPSDC series of shielded, surface-mount wire-wound inductors features a profile ranging from 2.92 mm, 5.08 mm, to 7.62 mm, and is suited for use in low-profile DC-DC converters and switch-mode power supplies used in power telecommunications systems, industrial controls, and medical instrumentation.

All parts are magnetically shielded to avoid electromagnetic interference with surrounding circuitry. Electrical parameters include an inductance of 1.0 μH to 10000.00 μH, resistance of 0.021 ohms to 32.800 ohms, and a rated current of 0.02A to 8.00A. The inductors also operate from -40°C to +85°C.

The power shielded inductors are wound around a ferrite core and are particularly suitable for cost-critical mass applications and the surface-mounting capability. The TPSDC series conform to the RoHS directive and Lead-free. Custom parts are available on request for tighter tolerances. Application of shielded inductors specific designs also available including different inductance and frequency specifications adjusted to requirements.
