Fixed Inductors Procurement Notes

Verify the specific suffix 'K' against official API Delevan documentation to confirm tolerance and material specifications. Ensure procurement channels source directly from authorized distributors or the manufacturer to guarantee authenticity. Cross-reference the MIL-PRF-M15305 series compliance if military-grade qualification is required for the application environment.

Fixed Inductors Selection Notes

Select this component when a 6.8 µH inductance with a 185 mA current rating is required in an axial package. Consider the 2 Ohm DC resistance and self-resonant frequency characteristics relative to the target circuit frequency. Evaluate the -55°C to 105°C operating range against environmental constraints before finalizing the design.

Fixed Inductors Part Context
