AH-03

Overview

The Ohmite AH-03 is a single-phase EMC/EMI line filter module designed for power line noise suppression. It operates at rated currents ranging from 1A to 50A with voltage ratings of 110VAC and 250VAC at 50/60Hz frequencies. The component utilizes a two-stage filtering architecture to ensure effective interference reduction. Electrical testing includes a high potential test voltage specification for L-N configurations, ensuring robust insulation performance under operational stress conditions.

Feature Summary

• Dual-stage filtering architecture for enhanced noise attenuation
• Single-phase configuration suitable for standard AC power lines
• Quick-connect termination style for simplified assembly integration

Applications

• Power supply input stages requiring EMI suppression
• Industrial equipment noise mitigation
• Consumer electronics power line protection

Procurement Notes

Verify the specific current rating variant required for your application, as the AH-03 series spans 1A to 50A ranges. Confirm that the 110V or 250VAC rating aligns with your system voltage. Ensure the quick-connect terminal type matches your wiring harness specifications before finalizing procurement decisions.

Selection Notes

Select this component when single-phase EMI filtering is necessary for power inputs. Consider the dual-stage design for applications demanding higher attenuation levels. Verify that the operating frequency range of 50/60Hz matches your local power grid standards and that the physical form factor fits the intended enclosure space.
