Overview
The HBWS1005-20NJ is a fixed wirewound inductor manufactured by Max Echo Technology Corp. It features a non-shielded design with an inductance value of 20 nH. The component is housed in a standard 0402 (metric 1005) surface-mount package, suitable for compact circuit layouts. Key electrical specifications include a maximum DC resistance of 250 mOhm and a maximum current rating of 420 mA. These parameters define its operational limits within power and RF applications requiring low-profile magnetic components.
Feature Summary
- Non-shielded wirewound construction for specific electromagnetic interference profiles
- Compact 0402 footprint enabling high-density PCB integration
- Low DC resistance characteristic supporting efficient power transmission
Applications
- RF circuit filtering
- Power supply input/output stages
- General-purpose signal conditioning
Procurement Notes
Verify the exact part number against official Max Echo documentation to ensure compatibility with your design requirements. Confirm that the non-shielded configuration aligns with your system's EMI constraints. Cross-reference the 20 nH inductance and 420 mA current rating with your schematic specifications before finalizing procurement decisions.
Selection Notes
Choose this component when a small form factor is required alongside precise low-inductance performance. The 0402 size suits space-constrained designs. Ensure the 420 mA current limit meets peak load demands. Consider the non-shielded nature if adjacent components are sensitive to stray fields or if shielding is provided elsewhere in the assembly.
Part Context
Max Echo Technology Corp., established in 1992, specializes in SMD multilayer inductors and beads. The HBWS series represents their wirewound offerings, distinct from their multilayer ferrite lines like the PDLS series. This manufacturer focuses on magnetic materials and LTCC processes for industrial and automotive markets.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided source material. Consult distributor databases for cross-references based on identical 20 nH, 0402, and 420 mA specifications.
