FN2070B-36-08

Overview

The FN2070B-36-08 is a single-phase, two-stage EMI/EMC power line filter manufactured by TE Connectivity Schaffner. It features a rated current of 36 A and operates at voltages up to 250 VAC or 110 VAC. The device supports frequencies from DC to 400 Hz and utilizes threaded stud (M4) terminals for input and output connections. Designed for chassis mounting, it provides high differential and common-mode attenuation with excellent thermal behavior due to chokes with high saturation resistance.

Feature Summary

• Two-stage architecture providing high conducted attenuation performance
• Medical B-type configuration designed for low leakage current requirements
• Robust thermal management via chokes with high saturation resistance

Applications

• Medical equipment requiring strict safety isolation
• Industrial machinery power supplies
• General purpose AC/DC power conditioning systems

Procurement Notes

Verify the specific suffix 'B' confirms the medical-grade variant without Y-capacitors if low leakage is required. Confirm M4 threaded stud termination compatibility with your chassis interface. Ensure the 36A rating aligns with peak load demands within the -25°C to +100°C operating range.

Selection Notes

Select this model when high attenuation is needed in a compact chassis-mount form factor. The B-version is distinct from standard variants due to its medical certification and reduced capacitance. Compare against the FN2070 series for general industrial use if medical compliance is not mandatory.

Part Context

This component belongs to the FN 2070 multi-stage performance family. It is engineered for easy and fast installation on equipment chassis. The series offers various current ratings from 1 to 36 A, with the B-series specifically addressing safety-critical applications necessitating low leakage currents.
