ST-101

Overview

The KEMET ST-101 is a through-hole common mode choke belonging to the ST series. It features a toroidal ferrite core design intended for DC line filtering applications. The component provides a common mode impedance of 3 kOhms at 500 kHz and supports a maximum current rating of 200 mA. Its physical dimensions are compact, with a maximum height of 18 mm and a diameter of 18 mm. The device utilizes a proprietary ferrite formulation to achieve effective noise suppression in signal and power lines.

Feature Summary

Through-hole toroidal construction for robust mechanical mounting
Proprietary ferrite material for effective common mode noise attenuation
Designed specifically for DC line filtering applications

Applications

DC line filtering
Signal line noise suppression
Common mode interference reduction

Procurement Notes

Verify the specific datasheet revision and electrical characteristics against the manufacturer's official documentation before integration. Confirm that the through-hole package dimensions and lead configuration match the target PCB layout requirements. Ensure the 200 mA current rating and 3 kOhm impedance specifications meet the circuit's operational needs.

Selection Notes

Select this component when a through-hole solution is required for common mode noise suppression on DC lines. The ST-101 offers a balance of low DC resistance and high impedance at 500 kHz. Consider the physical size constraints and the need for flexible termination or standard leads based on the assembly process.

Part Context

The ST-101 is part of KEMET's broader ST series of common mode chokes. This series includes various components with different current ratings and impedance profiles, all sharing the same toroidal through-hole form factor. The series is designed to provide reliable EMI/RFI filtering solutions across a range of industrial and consumer electronic applications.
