Procurement Notes
Verify the specific manufacturer designation, as sources cite both Signal Transformer Company and Bel Signal Transformer. Confirm the impedance value matches the required circuit specifications of 90 Ohms at 100 MHz. Ensure the package type aligns with the PCB footprint requirements for surface mount installation.
Selection Notes
Select this component when automotive-grade reliability is required for signal lines. The low DC resistance minimizes power loss in high-current paths. The compact form factor suits space-constrained designs. Verify that the 400 mA current rating meets the operational demands of the target application without saturation.
Part Context
This part belongs to the SPDL Series II, designed for high-reliability environments. It serves as a passive filter component to suppress electromagnetic interference. The series offers various impedance values to suit different frequency attenuation needs in electronic circuits.
Replacement Considerations
Check for direct substitutes within the same series offering identical 90 Ohm impedance and 400 mA rating. Ensure any replacement maintains AEC-Q200 certification if used in automotive contexts. Verify physical dimensions match the existing PCB layout.
