1539M27

Overview

The Hammond Manufacturing 1539M27 is a fixed inductor belonging to the 1539 series, designed as an RF choke and heavy-duty hash choke. It features a drum core construction with wirewound technology and is unshielded. The component utilizes a radial vertical cylinder package for mounting. Key electrical specifications include an inductance of 250 µH and a maximum DC current rating of 9 A. The device exhibits a maximum DC resistance of 40 mOhm.

Feature Summary

• Heavy-duty hash choke design suitable for demanding RF applications
• Unshielded drum core construction with wirewound winding technique
• Radial vertical cylinder package configuration for standard mounting

Applications

• RF choke circuits
• EMI/RFI suppression
• Filter choke applications

Procurement Notes

Verify the complete part number including any suffixes against the manufacturer's official datasheet to ensure exact specification matching. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to ordering, as availability may vary by region.

Selection Notes

Select this component when a high-current RF choke with 250 µH inductance is required. Ensure the application environment accommodates the unshielded nature of the drum core. Verify that the radial vertical package fits the PCB layout constraints and that the 9 A current rating meets the circuit's operational demands.

Part Context

This part is manufactured by Hammond Manufacturing, a producer known for industrial enclosures, electronic enclosures, racks, transformers, and outlet strips. The 1539 series specifically addresses inductor needs within their broader portfolio of electronic components and hardware solutions.

Replacement Considerations

Consult official Hammond Manufacturing documentation for confirmed substitute part numbers. Do not assume cross-compatibility with other manufacturers' RF chokes without verifying inductance, current rating, and physical dimensions against the original specifications.
