FN2020A-20-06

Overview

The Schaffner FN2020A-20-06 is a single-phase EMI/EMC power line filter designed for chassis mounting. It supports a rated current of 20 A and operates at AC voltages up to 250 V. The component functions within a frequency range of DC to 400 Hz and utilizes a two-stage configuration for noise attenuation. Termination is achieved via fast-on connectors, ensuring secure electrical connections. The unit is certified by CSA, CQC, ENEC, and UR, indicating compliance with international safety standards.

Feature Summary

• Metal enclosure construction provides optimal earth connection and high-frequency performance
• Two-stage internal circuit design enables effective attenuation of electromagnetic interference
• Fast-on terminal style facilitates rapid integration into equipment power inputs

Applications

• Industrial machinery power supplies
• Medical equipment input stages
• Information technology hardware filtering

Procurement Notes

Verify the specific voltage rating and current capacity against the target application requirements before procurement. Confirm that the fast-on connector dimensions match the mating terminals on the host system. Ensure the chassis mounting holes align with the available space in the equipment enclosure. Check for required certification marks such as UL or CE based on regional regulations.

Selection Notes

Select this model when a robust metal-cased filter is required for high-current applications up to 20 A. The two-stage architecture offers superior noise suppression compared to single-stage alternatives. Consider the physical dimensions and chassis mounting constraints during the design phase. Verify compatibility with the operating temperature range of -25°C to 100°C for the intended environment.
