FN2070-36-08

Overview

The Schaffner FN2070-36-08 is a single-phase, two-stage EMI/EMC power line filter designed for chassis mounting. It features threaded stud input and output terminations with M4 thread specifications. The component supports rated currents up to 36 A at 40°C and operates within a frequency range of DC to 400 Hz. It is rated for AC voltages of 110 V and 250 V. The filter utilizes chokes with high saturation resistance to provide high differential and common-mode attenuation.

Feature Summary

• Multi-stage architecture providing high conducted attenuation performance based on chokes with high saturation resistance.
• Designed for easy and fast chassis mounting using threaded stud connections.
• Capable of handling high current loads while maintaining excellent thermal behavior.

Applications

• Industrial equipment requiring robust EMI suppression
• Power supply units needing high-current filtering
• Medical devices (specific B-type variants in the series)
• Safety-critical applications (specific A-type variants in the series)

Procurement Notes

Verify the specific termination style and current rating requirements against the official datasheet before ordering. Confirm that the chassis mounting holes align with the physical dimensions provided in the mechanical drawings. Ensure the operating environment temperature remains within the specified limits to maintain the 36 A rating. Check for any required safety certifications such as UL or CSA depending on the target market regulations.

Selection Notes

Select this model when a single-phase filter with high current capacity is required. The threaded stud terminals are suitable for heavy-duty connections compared to quick-connect options. Consider the two-stage design for superior noise attenuation compared to single-stage alternatives. Verify if the standard version meets leakage current requirements or if a specialized medical or safety variant is necessary for the application.

Part Context

This component belongs to the FN 2070 series of multi-stage performance AC/DC EMI filters. The series offers rated currents ranging from 1 A to 36 A. Variants include B types without Y-capacitors for medical applications and A types with low capacitance for safety-critical uses. All models share the core design principle of high-frequency attenuation using high-saturation-resistance chokes.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Alternative solutions may require custom engineering or selection from different series with similar current and voltage ratings but potentially different termination styles.
