1539M32

Overview

The Hammond Manufacturing 1539M32 is a fixed wirewound inductor from the 1539 Series, designed for EMI/RFI suppression and DC link applications. It features an unshielded drum core construction with radial vertical cylinder packaging. The component provides an inductance of 10 mH and supports a current rating of 1.5 A. Its maximum DC resistance is specified at 1.55 Ohms. The unit utilizes lead wires with a diameter of 0.053 inches and maintains a conductor spacing of 1.25 inches.

Feature Summary

• Unshielded drum core design for general electromagnetic interference suppression
• Radial vertical cylinder mounting configuration for standard PCB integration
• Wirewound construction suitable for industrial automation and power filtering

Applications

• EMI/RFI chokes in enclosed rack systems
• Floor stationary equipment filtering
• DC link choke applications in industrial automation

Procurement Notes

Verify the specific datasheet version when ordering, as manufacturing specifications may evolve. Confirm that the radial lead spacing matches your board layout requirements prior to procurement. Ensure the unshielded nature of the component aligns with your system's electromagnetic compatibility constraints. Cross-reference the manufacturer part number directly to avoid confusion with similar series variants.

Selection Notes

Select this component when a 10 mH inductance value is required for low-frequency noise attenuation. The 1.5 A current rating defines its operational limit for continuous duty cycles. Consider the unshielded design if space constraints preclude larger shielded alternatives, but account for potential radiated emissions in sensitive environments. The radial package dictates specific hole-punching or through-hole assembly processes.

Part Context

This component belongs to the Hammond 1539 Series, which specializes in EMI and RFI chokes. The series offers various inductance values tailored for different filtering needs. The 1539M32 specifically addresses applications requiring moderate inductance with robust wirewound durability. It serves as a passive filtering element within broader power management and signal integrity circuits.

Replacement Considerations

Consult official Hammond Manufacturing documentation for direct cross-references. Verify that substitute components match the 10 mH inductance, 1.5 A current rating, and 1.55 Ohm resistance limits. Ensure physical dimensions and lead spacing compatibility before substitution.
