Fixed Inductors Procurement Notes

Verify the specific ordering suffix to confirm the exact inductance value and tolerance level, as variations exist within the series. Ensure the selected variant meets the required DC resistance and current rating for the target application. Cross-reference the manufacturer's latest datasheet to confirm package dimensions and terminal compatibility before finalizing procurement.

Fixed Inductors Selection Notes

Select this component when precise inductance control is critical due to its narrow ±2% tolerance. The 680 nH value and 350 MHz self-resonant frequency make it suitable for high-frequency signal paths. Evaluate the 400 mA current rating against peak load requirements to prevent saturation. The 1008 footprint offers a balance between size constraints and power handling capabilities.

Fixed Inductors Part Context

This part belongs to the WW IND series of fixed inductors from Cal-Chip Electronics. These components are designed for general-purpose use in compact electronic devices. The series emphasizes reliability and consistent electrical characteristics across various operating temperatures, supporting diverse consumer and industrial electronics applications.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 680 nH inductance, ±2% tolerance, and 1008 package dimensions. Verify that alternative components meet or exceed the 1.61 Ω DCR limit and 400 mA current rating. Check for equivalent self-resonant frequency and Q factor to ensure RF performance compatibility.
