FN2070M-3-06

Overview

The Schaffner FN2070M-3-06 is a single-phase, two-stage EMI/EMC power line filter designed for chassis mounting. It features a rated current of 3 A and operates at voltages up to 250 VAC or 110 VDC. The component utilizes fast-on terminals for connection and supports frequencies from DC to 400 Hz. Certified under UL, CSA, and IEC/EN standards, it provides high differential and common-mode attenuation suitable for sensitive electronic equipment.

Feature Summary

• Two-stage filtering architecture providing high differential and common-mode attenuation
• Chassis mount design with fast-on terminal connections for rapid installation
• High saturation resistance chokes ensuring excellent thermal behavior

Applications

• Medical equipment requiring low leakage current configurations
• Industrial control systems operating at 400 Hz
• Sensitive electronic instrumentation

Procurement Notes

Verify the specific suffix code against official datasheets to confirm terminal type and voltage ratings. Ensure compatibility with chassis mounting requirements and fast-on connector specifications. Confirm certification status (UL, CSA, IEC/EN) matches application regulatory needs before procurement.

Selection Notes

Select this model for applications requiring single-phase filtering with a 3 A rating. Consider the fast-on termination style for board integration. Evaluate the two-stage performance benefits over single-stage alternatives for superior noise suppression in critical environments.

Part Context

Part of the FN2070 series, which offers multi-stage performance filters rated from 1 to 36 A. The series includes variants for medical (B-type) and safety-critical (A-type) applications, emphasizing high-frequency attenuation and robust thermal management through specialized choke designs.

Replacement Considerations

Consult official substitution guides for equivalent current ratings and terminal styles. Verify that alternative components match the two-stage topology and chassis mounting dimensions to ensure functional parity.
