EXC-14CP121U

Common Mode Chokes Overview

The EXC-14CP121U is a surface-mount common mode choke manufactured by Panasonic Electronic Components. It features a compact 0302 package size and provides an impedance of 120 ohms at the specified frequency. The component is designed for two-line applications with a rated current capacity of 300 mA. It serves as a noise filter to suppress electromagnetic interference in high-density circuit designs.

Common Mode Chokes Feature Summary

• Compact 0302 surface-mount footprint for space-constrained layouts
• Dual-line configuration for balanced signal integrity
• Integrated common mode noise filtering capability

Common Mode Chokes Applications

• High-speed data line protection
• Portable electronic device circuits
• Automotive infotainment systems

Common Mode Chokes Procurement Notes

Verify the exact suffix and manufacturer documentation before integration. Confirm that the 0302 package dimensions align with your PCB land pattern. Ensure the 300 mA current rating meets your specific circuit requirements. Cross-reference the datasheet for impedance characteristics at target frequencies to validate performance.

Common Mode Chokes Selection Notes

Select this component when a minimal footprint is required for common mode suppression. The 120 ohm impedance value suits moderate noise environments. Consider the 300 mA current limit for low-power signal lines. Evaluate thermal constraints given the small physical size during high-frequency operation.

Common Mode Chokes Part Context

This part belongs to Panasonic's series of passive components designed for modern electronics. It addresses the industry demand for smaller, more efficient filters in consumer and automotive sectors. The 0302 size represents a significant reduction compared to traditional through-hole or larger SMD chokes.

Common Mode Chokes Replacement Considerations

Check for direct substitutes from other manufacturers offering identical 0302 dimensions and 120 ohm impedance. Verify current ratings and DC resistance values match the original design specifications. Ensure compatibility with automated pick-and-place equipment due to the small form factor.
