EXC-24CH500U

Common Mode Chokes Overview

The Panasonic EXC-24CH500U is a surface-mount common mode noise filter designed for high-frequency signal integrity. It features a dual-channel configuration with an impedance of 50 ohms at 100 MHz and a tolerance of ±25%. The component supports a maximum DC current of 160 mA and has a maximum DC resistance of 1.75 ohms. It operates within a temperature range of -40°C to +85°C and utilizes a compact 0504 (1210 metric) package measuring 1.25 mm in length, 1 mm in width, and 0.5 mm in height.

Common Mode Chokes Feature Summary

• Dual-channel architecture for simultaneous suppression of common mode noise on paired signal lines.
• Compact 0504 surface-mount footprint enabling dense PCB layout optimization.
• High-frequency attenuation characteristics optimized for data line protection.

Common Mode Chokes Applications

• High-speed serial interface noise filtering
• USB port signal line protection
• HDMI or DisplayPort common mode interference suppression

Common Mode Chokes Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm exact impedance and tolerance specifications. Confirm that the required operating temperature range aligns with the -40°C to +85°C rating. Ensure the PCB land pattern matches the 0504 package dimensions. Check for end-of-life status as some sources indicate potential discontinuation.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring common mode noise suppression for differential pairs carrying up to 160 mA. The 50-ohm impedance at 100 MHz makes it suitable for moderate-speed digital signals. Consider the low profile of 0.5 mm for space-constrained applications. Verify compatibility with reflow soldering profiles compatible with the specified thermal ratings.

Common Mode Chokes Part Context

This part belongs to the Panasonic EXC series of common mode chokes. These components are engineered to attenuate electromagnetic interference without significantly affecting the desired differential signal. The series offers various impedance values to match different frequency requirements while maintaining a consistent small form factor for widespread adoption in consumer electronics.

Common Mode Chokes Replacement Considerations

Consult official Panasonic substitution guides for verified equivalents. Cross-referencing requires matching impedance, current rating, and package dimensions. Generic substitutes may not provide identical high-frequency performance characteristics.
