Fixed Inductors Procurement Notes

Verify the specific ordering suffix K against the manufacturer's official datasheet to confirm tolerance and packaging specifications. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity. Cross-reference the RoHS compliance status with the latest regulatory documentation provided by Bourns Inc. prior to finalizing purchase orders.

Fixed Inductors Selection Notes

Select this component when a 220 µH inductance value is required for low-current applications up to 0.32 A. Consider the unshielded nature of the drum core for potential magnetic interference in sensitive layouts. Evaluate the 1.6 Ohm DC resistance against efficiency requirements and the 3.30 mm height constraint within the target enclosure space.
