Overview
The Hammond Manufacturing 1540M15 is a fixed inductor belonging to the 1540 series, designed as an RF choke and heavy-duty hash choke. It features a toroidal core with radial vertical open leads. The component provides an inductance of 1.6 mH (1600 uH) and supports a maximum DC current of 0.8 A. Its maximum DC resistance is specified at 1.27 Ohms. The device is unshielded and suitable for applications requiring robust filtering or energy storage.
Feature Summary
- Heavy-duty construction suitable for demanding industrial environments
- Toroidal design optimized for EMI/RFI filtering performance
- Radial vertical lead configuration for standard mounting
Applications
- EMI and RFI filtering circuits
- Energy storage inductors for switching power supplies
- DC link chokes in industrial automation systems
Procurement Notes
Verify the specific suffix against official Hammond Manufacturing documentation to confirm electrical tolerances and lead finish. Ensure the selected variant matches the required inductance value of 1.6 mH and current rating of 0.8 A for your circuit design. Cross-reference datasheet revisions to guarantee compatibility with existing assembly processes.
Selection Notes
Select this component when high-current handling capability and compact toroidal geometry are required for noise suppression. Consider the unshielded nature of the part regarding magnetic field interference with nearby sensitive components. Evaluate the radial lead spacing against PCB layout constraints before finalizing the design.
Part Context
This component is part of the Hammond Manufacturing 1540 series of fixed inductors. The series includes various inductance values and current ratings tailored for industrial and commercial electronic applications. The 1540M15 specifically addresses needs for robust RF choking and power supply filtering within a standardized form factor.
Replacement Considerations
Consult official Hammond Manufacturing substitution guides for verified equivalents. Generic replacements may not match the specific 1.27 Ohm resistance or 0.8 A current limits. Verify that alternative toroidal inductors maintain compatible physical dimensions and lead configurations for direct board integration.
