Fixed Inductors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the requested quantity aligns with standard shipping units defined in the latest datasheet. Cross-reference the part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when circuit design requires a 68 µH inductance value capable of handling up to 2.6 A of continuous current. Ensure the PCB layout accommodates the nonstandard physical dimensions of 12 × 12 × 8 mm. Verify that the thermal environment remains within the specified -40°C to +125°C operational limits to maintain reliability and prevent excessive temperature rise during operation.
