Fixed Inductors Procurement Notes

Verify the manufacturer part number against official Cal-Chip Electronics documentation to ensure authenticity. Confirm that the specific suffix matches the required 9 nH value and ±5% tolerance. Check for RoHS compliance markings on packaging. Ensure storage conditions adhere to moisture sensitivity levels specified in the datasheet to prevent degradation prior to assembly.

Fixed Inductors Selection Notes

Select this component for designs requiring extremely low inductance values in a compact 0402 footprint. Consider the self-resonant frequency limits when operating near RF bands. Evaluate the DC resistance impact on series insertion loss. Compare thermal stability requirements against the ceramic core specifications to ensure reliability under varying ambient temperatures.

Fixed Inductors Part Context

This inductor belongs to the WB series from Cal-Chip Electronics, which focuses on small-form-factor passive components. The series supports modern electronics trends toward miniaturization. It complements other SMD devices like resistors and capacitors in dense PCB layouts. The manufacturer emphasizes supply chain efficiency and consistent quality for surface-mount applications.

Fixed Inductors Replacement Considerations

Substitutes must match the 9 nH nominal value and 0402 package dimensions. Verify equivalent self-resonant frequency characteristics to maintain circuit stability. Ensure the replacement offers similar Q-factor performance at the target operating frequency. Cross-reference pinout and polarity if applicable, though standard inductors are typically non-polarized.
