EXC-CET222U

Overview

The Panasonic EXC-CET222U is a surface-mount EMI filter circuit designed for high-frequency noise suppression. It features a capacitance of 2200pF and supports a maximum rated current of 2A. The component operates within a frequency range of 35 MHz to 180 MHz, with a specific cutoff characteristic noted at 65 MHz in distributor listings. Physically, it measures 4.5 mm in length and 2.7 mm in height, making it suitable for narrow-pitch insertion applications where compact footprint is critical.

Feature Summary

• Designed for effective electromagnetic interference filtering in high-speed digital circuits
• Compact surface-mount package optimized for narrow-pitch board layouts
• Capable of handling up to 2A rated current for robust signal integrity

Applications

• High-speed data line protection in consumer electronics
• Noise suppression in mobile device interfaces
• EMI mitigation in compact computing hardware

Procurement Notes

Verify the exact datasheet version from Panasonic Electronic Components to confirm electrical tolerances and thermal ratings. Ensure the ordering suffix matches the required packaging format. Cross-reference the 2200pF capacitance value against your specific noise frequency requirements within the 35-180 MHz range before finalizing procurement.

Selection Notes

Select this component when space constraints require a low-profile SMD filter with moderate current handling capabilities. The 2200pF value targets specific mid-to-high frequency noise bands. Confirm that the 4.5mm x 2.7mm footprint aligns with your PCB silkscreen and pad design rules for reliable soldering.

Part Context

This part belongs to Panasonic's EXC series of chip EMI filters, which utilize LC or RC network topologies for noise reduction. The CET variant indicates a specific form factor within this family, engineered for automated assembly processes in modern electronics manufacturing environments.
