Procurement Notes

Verify the specific ordering suffix to confirm package type and quantity configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required inductance tolerance and current ratings for the target application environment.

Selection Notes

Select this component when an unshielded RF inductor with 150 nH nominal value is required. Consider the 880 mA current limit and 125 mOhms DCR for power handling requirements. Evaluate the 750 MHz self-resonant frequency against the operating bandwidth to ensure adequate performance margins for the intended RF design.
