Procurement Notes
Verify the manufacturer part number against official TAI-TECH documentation to ensure authenticity. Confirm that the received components match the specified 9.00mm x 7.00mm dimensions and RoHS compliance status. Check for physical damage to the terminals before integration into the circuit design.
Selection Notes
Select this component when a 4A current rating and 1kOhm impedance at 100MHz are required for common mode noise attenuation. Ensure the PCB footprint accommodates the 9.00mm x 7.00mm surface mount package. Verify that the operating temperature range of -40°C to 125°C meets the environmental requirements of the target application.
Part Context
This component belongs to the WCM series of wire-wound common mode filters from TAI-TECH. It is designed for surface mount technology applications requiring robust EMI suppression in compact spaces. The series typically includes various impedance and current ratings to suit different signal integrity needs.
Replacement Considerations
Cross-reference with other TAI-TECH WCM series parts such as WCM7060CLF2-400-M for similar form factors. Ensure substitute components maintain equivalent impedance characteristics and current handling capabilities to preserve circuit performance.
