Procurement Notes
Verify the manufacturer part number against official Bel Signal Transformer documentation to ensure authenticity. Confirm that the specific impedance value and current ratings match the circuit requirements. Check for RoHS compliance status if required by regulatory standards. Ensure the packaging format aligns with automated assembly capabilities.
Selection Notes
Select this component when space is limited and low-profile filtering is required. The 2012 footprint allows for dense board layouts. Ensure the operating current does not exceed 350 mA to maintain performance. Verify that the 180 Ohm impedance at 100 MHz meets the target frequency attenuation needs.
Part Context
This component belongs to the SPDL series of ultra-compact chokes designed for high-density applications. It is manufactured by Bel Signal Transformer, a provider of power and signal conditioning solutions. The series is characterized by small footprints and reliable performance in automotive and consumer electronics environments.
Replacement Considerations
Consult official substitution guides for equivalent components with matching impedance and current ratings. Verify pin compatibility and thermal characteristics before replacing. Ensure any substitute part meets the same environmental and mechanical specifications.
