High Current Inductors (TPSRH-103R/104R/105R)

TPSRH103R, TPSRH104R, and TPSRH105R provide wide inductance range from 1.20μH to 1000.00μH, low direct current resistance (DCR) down to 0.008Ω, and large current up to IDC 10.0A. These devices are directly connected electrode on ferrite core with excellent property and high saturation for surface mounting.

DeMint enhances SMD wirewound (TPSRH-63R/103R/104R/105R) family inductors covering complete footprint with profile from 1.8 mm to 8.0 mm, inductance from 1.00 μH to 1000.00 μH, low DCR, and Rated Current uo to 8.5A.

DeMint (TPSRH-63R/103R/104R/105R) 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. Custom parts are available on request. DeMint will also produce devices outside these specifications to meet specific customer requirements.

Application of specific designs also available including different inductance and frequency specifications adjusted to requirements. Contact our sales for more information.
