HBWS1005-4N3S

Overview

The HBWS1005-4N3S is a fixed wirewound inductor from Max Echo, housed in a compact 0402 (1005 Metric) surface-mount package. It features an inductance of 4.3 nH with a tolerance of ±0.3 nH. The component supports a maximum current rating of 700 mA and exhibits a maximum DC resistance of 91 mOhm. Designed for high-frequency applications, it operates within a temperature range of -55°C to 125°C. The unshielded construction facilitates integration into space-constrained circuit boards while maintaining stable electrical performance under varying thermal conditions.

Feature Summary

• Unshielded wirewound design for minimal magnetic interference
• Compact 0402 footprint for dense PCB layouts
• Stable inductance with tight tolerance specification
• High current handling capability relative to size

Applications

• RF signal path filtering
• Power supply output chokes
• High-frequency noise suppression circuits
• Impedance matching networks

Procurement Notes

Verify the specific suffix 'S' against the manufacturer's latest datasheet to confirm tolerance and packaging details. Ensure the ordering part number matches the required inductance value of 4.3 nH precisely. Cross-reference the DC resistance maximum of 91 mOhm with circuit requirements. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Check for any recent revisions to the EBMS or HBWS series documentation.

Selection Notes

Select this component when a low-inductance, unshielded solution is required for high-speed signals. The 0402 package suits applications with strict spatial limitations. Consider the 700 mA current rating to ensure adequate headroom for peak loads. The wide operating temperature range allows use in harsh environments. Evaluate the unshielded nature to prevent magnetic coupling issues in adjacent components.

Part Context

This inductor belongs to Max Echo's line of fixed passive components, specifically designed for surface-mount technology. The HBWS series typically targets applications requiring small form factors and reliable performance. As a wirewound type, it offers distinct characteristics compared to multilayer alternatives, particularly regarding current handling and Q-factor at specific frequencies.

Replacement Considerations

Direct substitutes must match the 4.3 nH inductance, 0402 package, and similar current ratings. Verify that alternative manufacturers offer unshielded variants if magnetic isolation is not desired. Ensure the replacement maintains the same tolerance level and DC resistance limits to preserve circuit integrity.
