Procurement Notes

Verify the exact suffix against official Panasonic documentation to confirm specific capacitance values, as variations exist within the EZA-CT series. Confirm current availability status directly with authorized distributors, as this component may be subject to discontinuation or stock limitations. Ensure the selected variant matches the required 12V rating and 0402 package dimensions for your design.

Selection Notes

Select this component when a four-channel low-pass filter is required for high-speed data lines in portable devices. The 1 kΩ resistance and 22 pF capacitance combination offers specific attenuation characteristics suitable for USB or similar interfaces. Ensure the 0402 package size fits the PCB layout constraints and that the 12V operating voltage aligns with the system power supply.

Part Context

This part belongs to the Panasonic EZA-CT series of RC network filters. These components are engineered for compact EMI suppression in consumer electronics. The CT designation typically indicates specific capacitance and package characteristics within the broader EZAST family, distinguishing it from other variants like the ST or NT series which may offer different electrical properties or form factors.

Replacement Considerations

Check Panasonic's official cross-reference lists for direct substitutes. Verify that any alternative maintains the 4-channel configuration, 1kΩ/22pF values, and 0402 footprint to ensure mechanical and electrical compatibility without redesigning the circuit board.
