EXC-CET271U

Overview

The EXC-CET271U is a surface-mount EMI filter circuit manufactured by Panasonic Electronic Components. It features an LC(T) topology with a capacitance value of 270pF and a cutoff frequency of 200MHz. The component supports a maximum rated current of 2A and operates at a voltage rating of 50V. Designed for narrow pitch insertion, it provides effective noise suppression in compact electronic assemblies.

Feature Summary

• LC(T) topology for efficient EMI/RFI noise filtering
• Optimized for narrow pitch board insertion
• Compact surface-mount design

Applications

• Noise suppression in high-density PCB layouts
• Signal integrity protection in consumer electronics
• EMI filtering in portable devices

Procurement Notes

Verify the obsolete lifecycle status before procurement planning. Confirm availability through authorized distributors as standard stock may be limited. Ensure the SMD package dimensions match the target PCB footprint. Validate that the 2A current rating and 50V voltage specifications meet the circuit requirements. Check for RoHS compliance documentation if required by project standards.

Selection Notes

Select this component when a 270pF capacitance and 200MHz cutoff frequency are required for EMI suppression. The 2A current rating suits applications with moderate power demands. The narrow pitch design is ideal for space-constrained boards. Verify compatibility with reflow soldering profiles typical for surface-mount components.

Part Context

This part belongs to Panasonic's EXC series of EMI filter circuits. The series offers multiple capacitance values tailored to specific noise frequencies. The EXC-CET271U specifically addresses mid-frequency noise attenuation needs in compact form factors.

Replacement Considerations

No public substitute part numbers are confirmed in available documentation. Consult Panasonic directly for equivalent recommendations given the obsolete status.
