• High-frequency performance optimized for RF applications
• Surface-mount design for automated PCB assembly

Applications

• RF circuit filtering
• Impedance matching networks
• Signal processing components

Procurement Notes

Verify the specific manufacturer datasheet to confirm exact physical dimensions, as the part number indicates a nonstandard package. Ensure that the 695 mA current rating and 200 mOhm resistance values align with your circuit requirements before finalizing procurement orders.

Selection Notes

Select this component when a low-inductance value near 180 nH is required for high-frequency signal paths. Consider the unshielded nature of the device regarding potential electromagnetic interference with adjacent traces. Verify that the nonstandard footprint matches your board layout constraints.

Part Context

This part belongs to the Delevan fixed inductor family designed for radio frequency environments. It serves as a passive energy storage element within electronic circuits, specifically engineered for stability and precision in high-frequency operations where standard inductors may not perform adequately.
