SMD Compact Power Toroidal Inductors (TPSTX) Shielded

DeMint Power Solutions has enhanced its toroidal surface-mount inductor portfolios with the addition of four new ranges (TPSTX-2P/2S/4P/4S) of RoHS compliant components.

This (TPSTX) Range of low EMI toroidal inductor is based on iron powder cores, for good suppression performance at high frequencies, high overload capability, low flux-leakage, economical pricing, and optimized for use as high frequency DC chokes.

These low cost surface-mount toroidal inductors meanwhile are designed for use in switching AC/DC power supplies and DC/DC converters. The (TPSTX) series offer low DC resistance and is available with current ratings up to 7.9 A IDC and inductance values that range from 0.49 uH to 1201.70 uH.

The height of TPSTX-2P and TPSTX-2S is 5.96 mm (Max.), and TPSTX-4P and TPSTX-4S is 7.00 mm (Max.). These low-profile design makes them ideal for use in designs where component height is restricted. The toroid core offers compact size with minimal external magnetic fields and is ideal for low voltage applications, particularly the latest generation of low voltage microprocessors.

Custom parts are available on request. Application of specific designs also available including different inductance and frequency specifications adjusted to requirements. Please contact our sales for more information.
