Overview
The Hammond Manufacturing 1539M22 is a heavy-duty RF choke from the 1539 series, designed for industrial applications. It features an unshielded drum core construction with a fixed inductance of 500 µH and a DC current rating of 5 A. The component utilizes through-hole mounting technology and exhibits a maximum DC resistance of 90 mΩ. This leaded inductor serves as an EMI/RF filter to suppress noise in electronic circuits.
Feature Summary
- Heavy-duty construction suitable for demanding industrial environments
- Unshielded drum core design for effective electromagnetic interference suppression
- Through-hole termination style for secure board integration
Applications
- Industrial automation control systems
- PLC input/output filtering stages
- Electronic equipment requiring RF noise attenuation
Procurement Notes
Verify that the required inductance value of 500 µH and current handling capacity of 5 A align with the circuit design specifications. Confirm that the through-hole package dimensions are compatible with the printed circuit board layout. Ensure the unshielded nature of the component does not interfere with adjacent sensitive traces or components within the enclosure assembly.
Selection Notes
Select this component when a robust, high-current RF choke is needed for industrial-grade noise reduction. The 5 A rating supports substantial load currents while maintaining signal integrity. Consider the physical size constraints of the PCB due to the through-hole footprint and the lack of shielding which may require careful placement relative to other circuit elements.
Part Context
This part belongs to the Hammond Manufacturing 1539 series of fixed inductors and chokes. The series offers various inductance values and current ratings tailored for different filtering requirements. The 1539M22 specifically addresses applications needing moderate inductance with high current tolerance, distinguishing it from lower-current surface-mount alternatives.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the 500 µH inductance, 5 A current rating, 90 mΩ resistance, and through-hole drum core form factor.
FAQ
Is the 1539M22 shielded?
