Introduction (TPSRH-124B/125B/127B)

Surface Mount Wirewound Inductors
TPSRH-124B/125B/127B series

Token four pin terminals flexible design Surface Mount Wirewound Inductor constructs with four terminal pin type which gives a flexible design as inductors or transformers (SEPIC, ZETA circuit, etc).

Provide wide inductance range from 6.8μH to 100.00μH, low direct current resistance (DCR) down to 26mΩ, and large current up to IDC 5.0A. These devices are directly connected electrode on ferrite core with excellent property and high saturation for surface mounting.

Token enhances surface mount inductor (TPSRH124B/125B/127B) family series covering complete footprint with profile from 1.8 mm to 8.0 mm, inductance from 1.00 μ to 1000.00 μ, low DCR, and Rated Current uo to 10.0A.

Token (TPSRH124B/125B/127B) with wire wound and magnetically shielded construction offers a variety of characteristics and high performace. Customers can select the optimum characteristics by choosing from footprint, DCR, and a wide range of inductance values and tolerances with some types offering magnetic shielding.

The series is lead-free and RoHS compliant. Application of specific designs also available including different inductance and frequency specifications adjusted to requirements.
