M-523CT

Common Mode Chokes Overview

The KEMET M-523CT is a surface-mount data line filter designed for noise countermeasures in DC signal circuits. It features a common mode choke configuration with two functions, rated for 50V and 1.5A current. The component utilizes proprietary ferrite cores to achieve an impedance of 200 Ohms at 20 MHz and a direct current resistance (DCR) of 65 mOhm. This SMD toroidal coil provides effective interference suppression while maintaining low insertion loss for the signal path.

Common Mode Chokes Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm electrical characteristics such as impedance frequency response and current ratings. Ensure the selected component matches the required voltage and current specifications for the target application. Cross-reference official KEMET resources for accurate mechanical dimensions and reflow soldering profiles.

Common Mode Chokes Selection Notes

Select this component when a surface-mount solution is required for attenuating common mode noise in low-voltage DC applications. Consider the 1.5A current rating and 50V maximum voltage limits during design. The low DCR ensures minimal impact on signal integrity, making it suitable for sensitive data lines where interference mitigation is critical without significant power loss.
