SMD High Frequency Power Inductors (TPUME) Unshielded

The DeMint (TPUME) latest devices offer the advantages of wirewound construction, and are designed with an iron core that features high saturation current and unshielded construction for high reilbility and great thermal stability.

DeMint Electronics has added new ranges of low-profile wire wound chip inductors, TPUME1206, TPUME1210L, TPUME1210, TPUME1812, and TPUME2220, for use in wireless communication equipments to increase flexibility of maximum height measurements with extended electrical characteristics.

The new (TPUME) series is designed to provide a good balance of performance and height within chip power miniature inductor offering. The TPUME1206 series is developed to have very compact footprint 3.2 mm x 2.3 mm with low profile 1.8 mm. The TPUME2220 series were developed to have a low DCR 0.039 ohm. Those TPUME family enables efficiency and flexibility.

All (TPUME) winding chip coils offer low DC resistance and large rated current. This is vital for computer product applications as it prevents energy dissipation from the chip inductor, improving the converter's overall efficiency.

The new ranges deliver a good size/performance ratio with low DC resistances from 0.039 Ω to 66.1 Ω. A wide range of inductances is also available from 1.0 μH to 2200 μH. The parts come with high rated currents up to 4 A, and feature magnetic unshielding as standard.

Custom parts are available on request. DeMint will also produce devices outside these specifications to meet specific customer requirements, please contact our sales for more information.
