EXC-24CH900UR

Common Mode Chokes Overview

The Panasonic EXC-24CH900UR is a surface-mount common mode noise filter and choke designed for high-speed differential data lines. It integrates an electrostatic discharge (ESD) suppressor circuit to protect sensitive electronics. The component operates within a temperature range of -40°C to +85°C. Key electrical parameters include a rated DC voltage of 5V, a maximum current rating of 130mA, and a DC resistance (DCR) of 2.5 Ohms. The impedance is specified as 90 Ohms at 100 MHz. It utilizes a compact 0504 package footprint.

Common Mode Chokes Feature Summary

• Integrates ESD suppression circuitry with common mode filtering capabilities
• Designed specifically for suppressing high-frequency noise in high-speed differential data lines
• Compact surface-mount construction suitable for space-constrained PCB layouts

Common Mode Chokes Applications

• High-speed differential data line protection
• Common mode noise suppression in electronic circuits
• Electrostatic discharge protection for sensitive components

Common Mode Chokes Procurement Notes

Verify the specific suffix UR against official Panasonic documentation to confirm packaging and tape-and-reel specifications. Confirm availability status as some variants in this series may be subject to end-of-life notices or production changes. Ensure compatibility with automated pick-and-place equipment regarding the 0504 package dimensions and moisture sensitivity level before finalizing procurement plans.

Common Mode Chokes Selection Notes

Select this component when simultaneous common mode noise attenuation and ESD protection are required on differential pairs. The 90 Ohm impedance at 100 MHz suits applications requiring moderate filtering characteristics. Verify that the 130mA current rating meets the operational requirements of the target circuit without causing excessive voltage drop due to the 2.5 Ohm DCR.

Common Mode Chokes Part Context

This part belongs to the Panasonic EXC series of EMC/ESD components. The series combines common mode chokes with TVS diodes for integrated protection. The EXC-24CH900UR represents a specific impedance variant within the 0504 package family, distinct from other series like EXC-24CS which may have different current ratings or pin configurations.
