Token TPSRB74
Product Introduction
Token Integrated E-Shield for Reduction of EMI In The
Compact Case Size.
Features :
Compact size.
Magnetically shielded.
Superior high Saturation for surface mounting.
Applications :
Power supply for VCRS, OA equipment Digital camera, LCD television set, notebook PC, portable
communication Equipments, DC/DC converters, etc.
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 5.6 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. 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.
Custom parts are available on request. Token will also produce devices outside these specifications to
meet specific customer requirements, Please contact our sales or link to Token official website “SMD
Power Inductors” for more information.
