Fixed Inductors Procurement Notes

Verify the specific suffix against official API Delevan documentation to confirm exact electrical tolerances and material composition. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity. Cross-reference the M83446/39-47F designation with current manufacturer releases to validate compliance status before finalizing orders.

Fixed Inductors Selection Notes

Select this component when an unshielded inductor is required for RF filtering or impedance matching in space-constrained designs. The 1812 footprint offers a balance between current handling and board area. Consider the 183 mA current rating and 6 Ohm DC resistance limits during circuit analysis to ensure performance stability under load conditions.

Fixed Inductors Part Context

This part belongs to the MIL1812/R series of fixed inductors manufactured by API Delevan. The series is characterized by its adherence to military standards, specifically M83446. These components are engineered for rugged environments where standard commercial inductors may fail due to thermal or mechanical stress.
