Procurement Notes
Verify the manufacturer part number SPDL3216-121-2P-T against official Signal Transformer documentation to ensure authenticity. Confirm that the specified impedance of 120 Ohms at 100 MHz and the 350 mA current rating align with your circuit requirements. Check for RoHS compliance status as indicated in the latest datasheet before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring common mode noise suppression for differential signals in automotive or multimedia applications. Ensure the PCB footprint matches the 3216 metric dimensions. Verify that the 350 mA saturation current meets the peak load demands of the protected lines without causing excessive insertion loss or thermal issues during operation.
Part Context
This component belongs to the SPDL series of surface mount common mode chokes manufactured by Signal Transformer. The series is engineered for compact electronic designs where space is limited but effective EMI filtering is critical. The SPDL3216-121-2P-T specifically targets applications needing moderate impedance characteristics for high-frequency noise attenuation.
Replacement Considerations
Consult Signal Transformer's official substitution guide for verified alternatives. Cross-reference impedance values and physical dimensions to ensure compatibility with existing PCB footprints and electrical performance requirements.
