FN2020B-6-06

Overview

The Schaffner FN2020B-6-06 is a single-phase EMI line filter rated for 6 A and 250 VAC/DC. Designed for chassis mounting, it operates within a frequency range of DC to 400 Hz. The component features faston terminals for connection. Key electrical parameters include an inductance of 7.8 mH and a capacitance of 150 nF. It has a leakage current of 740 μA and a power loss of 2.5 W at rated conditions. The unit measures 50.5 mm in length, 44.5 mm in width, and 29.3 mm in height.

Feature Summary

• Two-stage attenuation configuration for effective noise suppression
• Metal housing provides optimal earth connection and high-frequency performance
• Chassis mount design with faston terminals for secure installation

Applications

• Medical equipment power supplies
• Industrial control systems
• General purpose electronic devices requiring EMI filtering

Procurement Notes

Verify the specific suffix 'B' indicates medical compliance or specific certification requirements against the official datasheet. Confirm terminal type compatibility with mating connectors. Check for RoHS3 status and REACH compliance documentation. Ensure chassis mounting holes align with panel specifications. Validate operating temperature range suitability for the intended environment.

Selection Notes

Select this model for applications requiring single-phase filtering up to 6 A. The two-stage design offers higher attenuation than single-stage alternatives. Consider the physical dimensions for enclosure space constraints. Verify that the 740 μA leakage current is acceptable for sensitive medical or safety-critical circuits. Ensure the 400 Hz frequency rating matches the system power source.

Part Context

This component belongs to the Schaffner FN2020 series of AC/DC chassis filters. The series is characterized by metal cases for earth connection and space for multiple circuit stages. It is manufactured by TE Connectivity Schaffner. The product is designed for general purpose and medical applications where compact size and high performance are required.

Replacement Considerations

FN2060B-6-06: Similar 6 A single-phase filter with comparable ratings. FN2070B-6-06: Alternative with similar current and voltage ratings but potentially different inductance values. Verify pinout and mounting hole patterns before substitution.
