Iron core material for stable performance
Surface mount technology for automated assembly

Applications

RF circuit filtering
Impedance matching networks
High-frequency signal processing

Procurement Notes

Verify the End-of-Life (EOL) status confirmed by API Delevan on November 22, 2023. Confirm availability of alternative components from the same manufacturer series before finalizing procurement plans due to discontinuation.

Selection Notes

Select this component only if legacy compatibility is required. Evaluate equivalent unshielded RF inductors with similar 180 nH values and 710 mA ratings from active product lines to ensure long-term supply stability.

Part Context

This part belongs to the 105R series of RF inductors manufactured by API Delevan. It is designed for high-frequency applications requiring precise inductance values. The specific model indicates a 180 nH value encoded as '181' in the suffix.

Replacement Considerations

Consider the 4232R-181H or other active 105R series variants. Verify pinout and electrical parameters match the original design requirements when substituting discontinued parts.
