EXC-24CH900U

Common Mode Chokes Overview

The Panasonic EXC-24CH900U is a surface-mount common mode choke designed for high-frequency noise suppression. It features an impedance of 90 ohms at 100 MHz with a tolerance of +/-20%. The component supports a maximum DC current of 130 mA and has a maximum DC resistance of 2.5 ohms. It utilizes a compact 0504 (1210 metric) package, measuring approximately 1.25 mm in length, 1.0 mm in width, and 0.5 mm in height. The device operates within a temperature range of -40°C to +85°C.

Common Mode Chokes Feature Summary

• Provides effective attenuation of common mode electromagnetic interference in high-speed signal lines
• Utilizes a low-profile surface mount design suitable for space-constrained printed circuit boards
• Constructed with lead-free materials compliant with environmental directives

Common Mode Chokes Applications

• Noise filtering for USB data interfaces
• Signal line protection in portable electronic devices
• EMI suppression in consumer audio equipment

Common Mode Chokes Procurement Notes

Verify the specific suffix 'U' against the manufacturer's latest documentation to confirm compliance status and material composition. Confirm that the 130 mA current rating aligns with the target application's peak load requirements. Ensure the 0504 footprint matches the PCB layout specifications prior to finalizing procurement orders.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring common mode noise reduction for low-current signal paths. The 90 ohm impedance value is appropriate for frequencies around 100 MHz. Consider the 2.5 ohm DC resistance impact on signal integrity if the trace length is significant. The small form factor makes it suitable for dense board layouts where larger chokes cannot fit.

Common Mode Chokes Part Context

This part belongs to the Panasonic EXC series of common mode filters. These components are engineered for suppressing electromagnetic interference in digital communication lines. The series offers various impedance values and current ratings to suit different interface standards. The EXC-24CH900U specifically targets applications requiring moderate noise suppression in compact packages.

Common Mode Chokes Replacement Considerations

Cross-reference with other Panasonic EXC series parts such as EXC-24CE900U or EXC-28CE900U for alternative packaging or slight parameter variations. Verify pin compatibility and impedance curves before substituting with non-Panasonic equivalents.
