Overview
The Ohmite AH-20 is a single-phase, two-stage power line filter designed for electromagnetic interference suppression. It features a rated voltage of 250 VAC and a current rating of 20 A at 50/60 Hz. The unit utilizes chassis mount installation for secure integration into equipment enclosures. This component serves as an effective solution for filtering noise in AC power lines within industrial and commercial applications.
Feature Summary
- Single-phase dual-stage filtering architecture
- Chassis mount construction for stable installation
Applications
- Industrial machinery power conditioning
- Commercial electronic equipment noise suppression
- Medical device power line filtering
Procurement Notes
Verify the specific manufacturing date code against the obsolete status indicated in distributor records. Confirm that the 250 VAC / 20 A ratings align with the target system's electrical requirements before procurement. Ensure chassis mounting hardware compatibility with the intended enclosure design to guarantee proper mechanical stability during operation.
Selection Notes
Select this component when single-phase EMI/EMI filtration is required for circuits operating up to 20 A. The two-stage design offers enhanced attenuation compared to single-stage alternatives. Verify that the physical dimensions accommodate the available chassis space and that the thermal environment remains within operational limits for long-term reliability.
Part Context
This filter belongs to Ohmite’s lineup of power line filters, which are engineered for robust performance in demanding environments. The AH-20 specifically addresses common mode and differential mode noise in single-phase AC systems. It complements other Ohmite components used in power management and signal integrity applications across various industries.
Replacement Considerations
Public sources indicate this part number is obsolete. Engineers should consult Ohmite’s current product portfolio for equivalent single-phase, two-stage filters with matching 20 A and 250 VAC ratings. Verify pinout and mounting hole patterns to ensure mechanical interchangeability with existing designs.
