AMI-21B-3-3

Overview

The AMI-21B-3-3 is a single-stage, single-phase EMC/EMI line filter module manufactured by Altran Magnetics, LLC. It features a rated current of 3 A and operates within a voltage range of 250 VAC DC ~ 400 Hz. The unit utilizes quick connect terminals for circuit integration and is designed for chassis mounting. Key electrical specifications include a maximum capacitance of 0.68 uF and an inductance of 1.7 mH. The device supports a temperature range from -10°C to +40°C and weighs approximately 19 g.

Feature Summary

• Single-stage filtering architecture for EMI/EMC noise suppression
• Quick connect terminal interface for simplified assembly
• Chassis mount design for secure installation

Applications

• General electronic equipment power input filtering
• Industrial control systems requiring EMI suppression
• Medical device power supply stages

Procurement Notes

Verify the specific datasheet version for the AMI-21B-3-3 to confirm RoHS compliance status and exact dimensional tolerances before finalizing designs. Ensure that the operating environment remains within the specified -10°C to +40°C range to maintain performance integrity. Cross-reference the quick connect terminal specifications with mating connector requirements to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component when a compact, single-phase solution is required for low-current applications up to 3 A. The 250 VAC rating makes it suitable for standard mains-powered devices. Consider the 1.7 mH inductance value for expected attenuation characteristics at target frequencies. Verify that the chassis mounting style aligns with the enclosure design constraints and available space for the 55 mm length dimension.

Part Context

This part belongs to the AMI series of power line filter modules from Altran Magnetics, LLC. The series provides various current ratings and configurations for different electromagnetic interference mitigation needs. The AMI-21B-3-3 specifically addresses the 3 A requirement segment, offering a balance between size and filtering capability for general-purpose electronics.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate other AMI series variants or comparable single-stage filters from Altran Magnetics based on matching 3 A current, 250 VAC voltage, and quick connect terminal interfaces. Verify inductance and capacitance values to ensure equivalent filtering performance.
