AH-L12

Overview

The Ohmite AH-L12 is a single-phase EMC/EMI line filter module designed for chassis mounting. It operates at rated AC voltages of 110V and 250V with a current rating of 1A. The unit features a two-stage configuration to suppress electromagnetic interference across power lines. It supports operating frequencies of 50 Hz and 60 Hz. Termination is achieved via tab connectors, and the leakage current is specified at 340 uA.

Feature Summary

• Two-stage filtering architecture for enhanced noise suppression
• Chassis mount design for secure installation
• Tab connector termination style

Applications

• Power line filtering in electronic equipment
• EMC/EMI suppression in AC power inputs
• Industrial control systems requiring noise reduction

Procurement Notes

Verify the part status carefully as sources indicate this model may be obsolete. Confirm compatibility with specific voltage ratings (110V/250V) and current requirements (1A). Ensure the chassis mounting style and tab connector terminations match the system design constraints before procurement.

Selection Notes

Select this component when a single-phase, two-stage EMI filter is required for low-current applications up to 1A. It is suitable for environments needing chassis-mounted solutions with tab connections. Verify that the 340 uA leakage current meets safety standards for the intended application.

Part Context

The AH-L12 belongs to the AH series of power line filter modules manufactured by Ohmite. This series provides specialized components for managing electromagnetic interference in AC power circuits. The AH-L12 specifically addresses single-phase applications with defined voltage and current limits.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the potential obsolete status indicated in some sources, direct replacement verification against current manufacturer catalogs is recommended.
