• General purpose RF inductance

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with standard SMT assembly processes and check for RoHS compliance status in the latest datasheet before procurement.

Selection Notes

Select this component for applications requiring a 47 nH inductance value with high-frequency performance up to its self-resonant frequency. Consider the 820 mA current rating and low DC resistance for power handling requirements. The unshielded nature requires careful PCB layout to prevent coupling with nearby components.
