Overview
The Hammond Manufacturing 1538M21 is a fixed inductor from the 1538 series, designed as a heavy-duty hash choke. It features an unshielded wirewound construction with radial horizontal cylinder packaging. The component provides an inductance of 5 µH and supports a DC current rating of 23 A. Its maximum direct current resistance (DCR) is specified at 4 mΩ. The device utilizes ferrite material for its core and operates at a test frequency of 1 kHz with a tolerance of 10%.
Feature Summary
- Heavy-duty hash choke design for robust performance
- Unshielded wirewound construction using ferrite core
- Radial horizontal cylinder package configuration
Applications
- RF filtering applications requiring high current handling
- Power supply circuits needing stable inductance
- Industrial electronic equipment chassis integration
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct tolerance and lead configuration. Confirm that the radial horizontal package style matches your PCB layout requirements. Check for any recent revisions to the 1538 series specifications before finalizing procurement orders.
Selection Notes
Select this component when a 5 µH inductance value is required alongside a 23 A DC current capacity. The low DCR of 4 mΩ makes it suitable for efficiency-critical power paths. Ensure the unshielded nature does not interfere with nearby sensitive components due to potential magnetic field exposure.
Part Context
This part belongs to Hammond Manufacturing's 1538 series of fixed inductors. The series is characterized by heavy-duty construction suitable for industrial environments. Hammond specializes in enclosures and passive components, positioning this inductor within their broader portfolio of reliable electronic hardware solutions.
Replacement Considerations
Consult official distributor cross-reference tools for compatible parts. Verify that substitute components match the 5 µH inductance, 23 A current rating, and 4 mΩ DCR specifications. Ensure physical dimensions and terminal configurations are compatible with existing assembly processes.
