EXC-34CE670U

Common Mode Chokes Overview

The EXC-34CE670U is a surface-mount common mode choke filter from Panasonic Industry, designed for high-frequency noise suppression in compact electronic assemblies. Housed in an 0805 (2012 metric) package with dimensions of 2.0 mm x 1.25 mm x 0.5 mm, this component provides effective electromagnetic interference mitigation. It features a nominal impedance of 67 Ohms at 100 MHz with a tolerance of ±30%. The device supports a maximum DC current of 250 mA and maintains a maximum DC resistance of 800 mOhms. Operating within a temperature range of -40°C to +85°C, it utilizes SMD/SMT termination for reliable PCB integration.

Common Mode Chokes Procurement Notes

Verify the specific suffix 'U' against the manufacturer's official datasheet to confirm terminal configuration and material composition. Ensure the selected packaging format aligns with automated assembly requirements. Cross-reference the impedance value at 100 MHz with circuit simulation models for accurate performance prediction. Confirm RoHS compliance status through the latest regulatory documentation provided by Panasonic Industry.

Common Mode Chokes Selection Notes

Select this component when a 67 Ohm impedance at 100 MHz is required for common mode noise reduction. The 250 mA current rating must exceed the operational DC load of the target circuit. The 0805 footprint dictates board layout constraints; verify clearance against adjacent components. Consider the ±30% impedance tolerance during filter design to ensure adequate attenuation margins under varying manufacturing conditions.

Common Mode Chokes Part Context

This part belongs to the EXC34CG/CE series of common mode chokes manufactured by Panasonic Industry. The series offers various impedance values and package sizes to address diverse EMC requirements. The EXC-34CE670U specifically targets applications needing moderate impedance in a standard 0805 form factor, balancing performance with board space efficiency.

Common Mode Chokes Replacement Considerations

Direct substitutes include other 0805 common mode chokes with similar 67 Ohm impedance and 250 mA ratings. Verify pin compatibility and physical dimensions before substitution. Alternative Panasonic models within the EXC34CE series may offer different impedance values but share identical footprints.
