TPU×××A SMT Power Inductors
SMT Unshielded
Power Inductors
Token has extended range of power inductors
with new series (TPU×××A)
Preview
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..
