Overview
The HBWS1005-3N9S is a fixed inductor manufactured by Max Echo, designed for surface-mount applications. It features an unshielded wirewound construction housed in a 0402 (1005 Metric) package. The component provides an inductance of 3.9 nH with a tolerance of ±0.3 nH. It supports a current rating of 840 mA and has a maximum DC resistance of 66 mOhm. The self-resonant frequency is specified at 5.8 GHz, ensuring performance in high-frequency circuits.
Feature Summary
- Unshielded wirewound design suitable for high-frequency signal integrity
- Compact 0402 surface-mount footprint for space-constrained layouts
- High self-resonant frequency capability up to 5.8 GHz
Applications
- RF matching networks
- High-frequency filtering circuits
- Impedance matching stages in RF front-ends
Procurement Notes
Verify the specific suffix 'S' against the manufacturer's latest datasheet to confirm tolerance and packaging specifications. Ensure the ordering part number matches the required inductance value of 3.9 nH exactly. Cross-reference the DC resistance and current ratings with circuit requirements before finalizing procurement orders.
Selection Notes
Select this component when a low-inductance, high-frequency solution is required in a minimal footprint. The unshielded nature may necessitate careful PCB layout to minimize electromagnetic interference with adjacent traces. Verify that the 840 mA current rating meets the operational peak currents of the target application without saturation.
Part Context
This part belongs to the HBWS series of fixed inductors from Max Echo, which specializes in multilayer chip inductors and beads. The series offers various inductance values within the 0402 package size, catering to the demand for miniaturized passive components in modern electronic devices.
Replacement Considerations
Direct substitutes must match the 3.9 nH inductance, 0402 package, and similar electrical characteristics. Consult distributor databases for cross-references from other manufacturers offering unshielded wirewound inductors with comparable self-resonant frequencies.
