Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging configuration and tolerance specifications. Confirm that the requested variant matches the required impedance and current ratings for the target application environment. Cross-reference the RoHS compliance status and lead times directly with authorized distributors prior to finalizing procurement orders.
Selection Notes
Select this component when a low-profile, two-line common mode choke is required for high-frequency noise attenuation. The 1.2 A current rating and 120 mOhms DCR make it suitable for moderate current signal lines. Ensure the 4.50 mm x 3.20 mm footprint fits the PCB layout constraints and that the operating temperature range meets the system's thermal requirements.
