EXC-X4CH120X

Common Mode Chokes Overview

The Panasonic EXC-X4CH120X is a surface-mount common mode noise filter designed for high-density circuit boards. It features a compact 0202 package with dimensions of 0.65 mm length, 0.5 mm width, and 0.3 mm height. The component utilizes a ferrite core to suppress electromagnetic interference at a test frequency of 100 MHz. Key electrical specifications include an impedance of 12 Ohms with a tolerance of 20%, a maximum DC current rating of 100 mA, and a maximum DC resistance of 2.7 Ohms. It operates within a temperature range of -40°C to +85°C.

Common Mode Chokes Applications

• High-speed digital signal line noise suppression
• Portable electronic device circuit protection
• Communication interface EMI filtering

Common Mode Chokes Procurement Notes

Verify the specific impedance value and tolerance against the official Panasonic datasheet before integration. Confirm that the 100 mA current rating meets the operational requirements of the target circuit. Ensure the SMD/SMT termination style matches the PCB layout. Check RoHS compliance status if required by project specifications.

Common Mode Chokes Selection Notes

Select this component when a small form factor is critical for noise reduction in low-current signals. The 12 Ohm impedance offers specific attenuation characteristics at 100 MHz. Consider the unshielded nature of the part regarding potential coupling effects. Verify thermal stability within the specified -40°C to +85°C operating range for the intended environment.

Common Mode Chokes Part Context

This component belongs to the EXCX4CH series of common mode chokes from Panasonic Industry. The series focuses on miniaturized noise filters for modern electronics. It shares similar physical dimensions with other variants in the 0202 package family but differs in impedance values. The product falls under the broader category of inductors, chokes, and coils.

Common Mode Chokes Replacement Considerations

Direct substitutes must match the 0202 package size, 12 Ohm impedance, and 100 mA current rating. Verify pin compatibility and thermal characteristics. Consult manufacturer cross-reference lists for exact equivalents.
