HBWS1005-4N7S

Overview

The HBWS1005-4N7S is a fixed wirewound inductor from Max Echo, housed in a 0402 (1005 metric) surface-mount package. It features an inductance of 4.7 nH with a maximum DC resistance of 130 mOhm and a rated current of 640 mA. The component is unshielded and designed for high-frequency applications requiring compact form factors.

Feature Summary

• Unshielded wirewound construction suitable for general signal paths
• Compact 0402 footprint for dense PCB layouts
• Low DC resistance to minimize power loss

Applications

• RF circuit impedance matching
• High-speed data line filtering
• Power supply input/output decoupling

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to ensure correct tolerance and packaging configuration. Confirm that the unshielded design aligns with your electromagnetic interference requirements. Check RoHS compliance status and moisture sensitivity level prior to assembly planning.

Selection Notes

Select this component when a very low inductance value near 4.7 nH is required in a minimal 0402 package. Ensure the operating current does not exceed 640 mA to maintain performance. Consider the unshielded nature for layout spacing if adjacent components are sensitive to magnetic fields.

Part Context

This part belongs to Max Echo's HBWS series of ceramic chip inductors. It complements other low-inductance variants like the HBWS1005-2N7S within the same 0402 family, providing options for different circuit tuning needs while maintaining consistent physical dimensions.

Replacement Considerations

Direct substitutes include other 4.7 nH unshielded wirewound inductors in the 0402 package from manufacturers such as Murata or TDK. Verify that alternative parts meet the 640 mA current rating and 130 mOhm DCR specifications.
