A2T12 F

Overview

The Astrodyne TDI A2T12 F is a single-phase EMC/EMI power line filter designed for severe environments. It features a three-stage filtering architecture to ensure high attenuation performance. The unit supports a rated current of 12 A at 250 VAC and operates within a frequency range of 50/60 Hz as well as 50/400 Hz. It utilizes a quick connect interface for installation and functions reliably across an operating temperature range of -35°C to 55°C.

Feature Summary

• Three-stage filtering design for enhanced noise suppression
• Quick connect terminal interface for simplified integration
• Optimized for operation in severe environmental conditions

Applications

• General purpose industrial equipment
• Avionics systems requiring 400 Hz compatibility
• Military and defense electronics

Procurement Notes

Verify the specific datasheet version for the A2T12 F to confirm exact leakage current values and insertion loss curves, as these parameters define compliance with specific EMI standards. Ensure the mounting flange dimensions match the chassis cutout requirements before finalizing procurement orders.

Selection Notes

Select this component when high-density filtering is required in a compact form factor. The three-stage topology provides superior attenuation compared to single-stage alternatives. Verify that the 12 A current rating aligns with the maximum load requirements of the protected circuitry to prevent thermal overload during continuous operation.

Part Context

This model belongs to the A2T series, which is engineered for premium performance in harsh conditions. The series typically includes variants with different current ratings and connection types, all sharing a robust construction suitable for demanding applications where standard filters may fail due to vibration or temperature extremes.

Replacement Considerations

Direct substitutes must maintain the 12 A rating, 250 VAC voltage, and three-stage topology. Verify that any alternative part supports the same 50/400 Hz frequency range and quick connect interface to ensure mechanical and electrical compatibility without redesigning the enclosure.
