SMT Power Inductors Unshielded (TPUxxA)

Token has extended range of power inductors with new series (TPU×××A) Preview

Power Inductors SMT Unshielded - TPU75 series

Miniaturisation of today's electrical and electronic devices requires component manufacturers to increase the performance of components without increasing footprint. Token's latest (TPU×××A) wirewound chip inductor series offers improved performance in the same compact, low-profile case size.

The (TPU×××A) series is designed for DC-DC converter applications and features reduced DC resistance and increased allowable current. In DC-DC converters and power supplies, the performance of the power components directly affects the overall efficiency of the supply, so it is of paramount importance.

The TPU31A series of wirewound chip inductors is low profile at 1.1±0.3 mm maximum and is available in 1.0 uH to 120 uH denominations. The series features low DC resistance, down to 0.06 Ω, and high rated current; up to 1.4A is supported. All parts are low cast with open magnetic circuit construction and good for high mounting density.

Full (TPU×××A) series conform to the RoHS directive and Lead-free. Custom parts are available on request. Token will also produce devices outside these specifications to meet specific customer requirements, please contact our sales for more information.

Features :

Compact size and thin.
Open magnetic circuit construction.
The electrode with ferrite core directly, good for high mounting density.

Applications :

VTR, OA equipment, LCD television set, Notebook.
Portable communication equipments, DC/DC converters, etc..
