AP-03

Power Line Filter Modules Overview

The Ohmite AP-03 is a single-phase EMC/EMI line filter module designed for power line noise suppression. It features a current handling capacity of 3 A and operates at voltages up to 250 VAC (110V/250V) at 50/60Hz. The unit utilizes a single-stage filtering architecture with solder lead termination for PCB mounting, providing compact integration for electromagnetic interference mitigation in electronic systems.

Power Line Filter Modules Procurement Notes

Verify the specific voltage rating requirements against the 110V or 250VAC specifications before procurement. Confirm that the 3A current limit aligns with the circuit's operational load. Ensure the PCB layout accommodates the solder lead termination style and single-phase configuration. Cross-reference the manufacturer's datasheet for derating curves and thermal management guidelines to ensure reliable operation under expected environmental conditions.

Power Line Filter Modules Selection Notes

Select this component when a compact, single-phase solution is required for low-current applications up to 3A. It is suitable for environments where space constraints preclude larger through-hole filters. Consider the operating voltage range of 110V to 250VAC during selection. Evaluate the need for single-stage versus multi-stage attenuation based on specific EMI compliance targets.
