1538M07

Overview

The Hammond Manufacturing 1538M07 is a fixed wirewound inductor from the 1538 series, designed as an RF choke. It features an unshielded radial horizontal cylinder package with a leaded configuration. The component provides an inductance of 250 µH and supports a DC current rating of 4 A. Its maximum DC resistance is specified at 89 mΩ. This heavy-duty hash choke is constructed for robust performance in electronic circuits requiring reliable RF filtering.

Feature Summary

Heavy-duty construction suitable for demanding RF applications
Unshielded design to minimize magnetic interference with nearby components
Radial horizontal cylinder package for flexible PCB mounting orientations

Applications

RF filtering in communication equipment
EMI suppression in industrial control systems
Power supply input stages for noise reduction

Procurement Notes

Verify the specific manufacturer part number against official Hammond Manufacturing documentation to ensure authenticity. Confirm that the radial lead style and unshielded construction align with your circuit layout requirements. Check RoHS compliance status through the manufacturer's official datasheet or certified distributor channels before finalizing procurement decisions.

Selection Notes

Select this component when a high-current RF choke with 250 µH inductance is required. Ensure the PCB footprint accommodates the radial horizontal cylinder package dimensions. Consider the unshielded nature of the device during layout planning to prevent potential coupling issues with sensitive traces or adjacent components in dense assemblies.

Part Context

This inductor belongs to the 1538 series of heavy-duty hash chokes manufactured by Hammond Manufacturing. The series is characterized by robust wirewound construction intended for high-current RF applications. These components are distinct from shielded alternatives and are typically used where mechanical durability and high DC current handling are prioritized over magnetic containment.
