Procurement Notes

Verify the specific part number suffix against official TAI-TECH documentation to ensure correct impedance and current ratings. Confirm that the ordering code matches the required packaging format, such as tape and reel, if automated assembly is planned. Cross-reference distributor listings with manufacturer datasheets to validate authenticity and avoid counterfeit components. Ensure storage conditions align with moisture sensitivity levels specified in the product guidelines.

Selection Notes

Select this component when a small footprint is required for EMI suppression in high-density circuits. The 180 Ohm impedance at 100 MHz targets specific noise frequencies in data lines. Verify that the 350mA current rating meets the operational requirements of the protected circuit without saturation. Consider the -40°C to +125°C operating range for environments with significant thermal variations or self-heating during continuous operation.

Part Context

This component belongs to the WCM_V series of wire-wound common mode chokes from TAI-TECH. The series emphasizes compact dimensions and reliability for modern electronic devices. TAI-TECH utilizes over forty years of experience in magnetic materials to produce these elements.
