AH-L03

Power Line Filter Modules Overview

The AH-L03 is a single-phase EMC/EMI line filter module manufactured by Ohmite. It operates at a rated current of 3 A and a voltage of 250 V AC with a frequency range of 50/60 Hz. The device utilizes a two-stage filtering configuration to suppress electromagnetic interference. It features quick connect terminals for installation and is packaged in boxes.

Power Line Filter Modules Feature Summary

• Two-stage EMI/RFI suppression architecture
• Quick connect terminal interface
• Single-phase power line protection

Power Line Filter Modules Applications

• General purpose electronic equipment noise suppression
• Power supply input filtering
• EMC compliance enhancement for low-power devices

Power Line Filter Modules Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Ohmite or authorized distributors, as availability may vary. Confirm that the quick connect terminal type matches the target PCB or wiring harness specifications before procurement. Ensure the operating environment remains within the specified voltage and current limits.

Power Line Filter Modules Selection Notes

Select this component when a compact, single-phase solution is required for moderate current applications up to 3 A. The two-stage design offers enhanced attenuation compared to single-stage filters. Verify that the physical dimensions and terminal style fit the enclosure constraints. Consider thermal management requirements if the ambient temperature approaches operational limits.

Power Line Filter Modules Part Context

The AH-L03 belongs to Ohmite's AH Series of power line filter modules. This series is designed for general-purpose electromagnetic interference suppression in AC power lines. The product line supports various current ratings and voltage configurations to meet diverse industrial and commercial application needs.

Power Line Filter Modules Replacement Considerations

Check Ohmite's current catalog for updated AH Series equivalents. Verify that any substitute maintains the same 3 A rating, 250 VAC specification, and two-stage topology. Ensure terminal compatibility and mounting constraints are met by alternative parts.
