Fixed Inductors Procurement Notes

Verify the specific suffix designation against official API Delevan documentation to confirm exact tolerance and electrical characteristics. Ensure that the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity. Confirm RoHS compliance status and lot traceability requirements prior to ordering, as military-grade variants may have distinct handling protocols.

Fixed Inductors Selection Notes

Select this component when high precision and established reliability are required for RF applications. The 3.9 µH value and 80 MHz self-resonant frequency make it suitable for higher frequency signal paths. Consider the 263 mA current rating and 1 Ohm resistance for power loss calculations. Compare against standard tolerance variants if cost sensitivity outweighs the need for ±3% accuracy.
