EXC-24CP121U

Common Mode Chokes Overview

The EXC-24CP121U is a two-mode noise filter manufactured by Panasonic Industry, designed for high-current applications. It functions as a common mode choke with an impedance of 120 Ohms at 100 MHz and a maximum DC resistance of 300 milliohms. The component supports a current rating of 500 mA and operates within a temperature range of -40°C to +85°C. It utilizes optimally magnetic-coupled ferrite beads to filter both common and differential mode noise, making it suitable for audio circuits requiring burst and radiation noise suppression.

Common Mode Chokes Procurement Notes

Verify the specific datasheet version when sourcing, as Panasonic documents may vary slightly in formatting or revision dates. Confirm that the required impedance characteristics align with the 120 Ohm specification at 100 MHz for your specific application. Ensure the 500 mA current rating meets the operational requirements of the target circuit to prevent saturation or excessive heating.

Common Mode Chokes Selection Notes

Select this component when simultaneous attenuation of common and differential mode noise is required in high-current paths. The low DC resistance minimizes voltage drop across the filter. Consider the surface mount package dimensions and thermal performance if the operating environment approaches the upper limit of the specified temperature range.
