Procurement Notes
Verify the specific manufacturer designation, as this part number is associated with both Bel Fuse (Signal Transformer) and other distributors. Confirm RoHS compliance status and exact lead times directly with the authorized supplier or original manufacturer documentation before finalizing procurement plans.
Selection Notes
Select this component when a low-profile SMD choke is required for differential signal lines. Ensure the 300 mA current rating meets the circuit's operational requirements. Verify that the 500 Ohm impedance at the target frequency provides sufficient attenuation for the specific noise profile encountered in the application.
Part Context
This component belongs to the SPDL series of ultra-compact SMD common mode chokes. The series is designed to replace larger through-hole components, enabling higher density PCB layouts. It serves as a critical passive element for maintaining signal integrity in high-speed digital interfaces.
Replacement Considerations
Cross-reference with SPDL3225-220-2P-T for higher inductance needs or SPDL3225-110-2P for bulk packaging variations. Verify pin compatibility and impedance curves against alternative suppliers' offerings to ensure electrical equivalence.
