FN2020B-1-06

Overview

The Schaffner FN2020B-1-06 is a single-phase EMI line filter designed for chassis mounting. It supports a maximum current of 1 A and operates at voltages up to 250 V AC/DC with a frequency range extending to 400 Hz. The unit utilizes faston terminals for connection and features a metal case optimized for earth grounding. Key electrical parameters include a capacitance value of 150 nF, an inductance of 600 μH, and a leakage current of 740 μA. It functions within a temperature range of -25°C to 100°C.

Feature Summary

• Metal enclosure design ensures optimal earth connection and high-frequency performance
• Configurable internal space allows for up to three circuit stages to enhance noise attenuation
• Faston terminal style enables rapid installation and secure electrical connections

Applications

• Chassis-mounted power line filtering for electronic equipment
• Noise suppression in systems operating up to 400 Hz
• General EMC compliance for low-current AC/DC applications

Procurement Notes

Verify the specific suffix code against official datasheets to confirm terminal type and voltage ratings. Ensure the chassis mounting configuration matches the mechanical constraints of the target enclosure. Confirm that the faston terminal dimensions align with the mating connector specifications before finalizing procurement orders.

Selection Notes

Select this component when a compact, single-phase filter is required for currents up to 1 A. The metal housing provides superior shielding compared to plastic alternatives. Consider the 600 μH inductance and 150 nF capacitance values to ensure adequate attenuation for the specific noise spectrum present in the application environment.
