The component is housed in a compact 0402 (1005 Metric) surface-mount package, measuring 1.0 mm in length, 0.5 mm in width, and 0.5 mm in height. It has a maximum DC resistance of 100 mΩ and a rated current of 680 mA. The device is lead-free and RoHS compliant.

Fixed Inductors Feature Summary

• Unshielded drum core construction for minimal magnetic interference
• Compact 0402 surface-mount footprint for space-constrained designs
• Lead-free and RoHS compliant manufacturing process

Fixed Inductors Applications

• RF circuit impedance matching networks
• High-frequency signal filtering applications
• Miniaturized communication device modules

Fixed Inductors Procurement Notes

Verify the specific inductance value of 7.5 nH and the ±5% tolerance against project requirements. Confirm that the 0402 package dimensions align with the PCB land pattern. Ensure the 680 mA current rating meets the operational load. Check for RoHS compliance documentation if required by regulatory standards. Validate the unshielded nature of the component regarding nearby sensitive traces.

Fixed Inductors Selection Notes

Select this component when a low-inductance value is required for high-frequency RF applications. The unshielded design may necessitate careful layout to prevent magnetic coupling with adjacent components. Consider the 680 mA current limit to avoid saturation or thermal issues. The 0402 size is suitable for dense PCB layouts where space is limited compared to larger packages.

Fixed Inductors Part Context

This part belongs to the wirewound inductor category from Cal-Chip Electronics. It utilizes a drum core technology optimized for small form factors. The series offers various inductance values within the nano-Henry range, catering to RF front-end and high-speed digital filtering needs in modern electronic devices.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 7.5 nH inductance, 0402 package, and similar current ratings. Verify compatibility with existing PCB footprints. Cross-reference manufacturer datasheets for equivalent unshielded wirewound types.
