Procurement Notes

Verify the exact physical dimensions against your PCB footprint, as the datasheet classifies the package as non-standard. Confirm that the 36 mA current rating meets your circuit requirements. Check RoHS compliance status and lead finish specifications before finalizing procurement to ensure compatibility with your assembly process.

Selection Notes

Select this component when a high-inductance value is required in a compact SMD form factor. The unshielded nature may necessitate careful layout planning to minimize electromagnetic interference. Ensure the operating environment stays within the specified temperature limits and that the DC resistance does not cause excessive voltage drop.
