5500.2118

Overview

The Schurter 5500.2118 is a single-phase EMI filter circuit designed for PCB mounting. It operates at rated voltages of 125 VAC and 250 VAC with a current rating of 2 A at 50 Hz or 60 Hz. The component features a single-stage filtering architecture utilizing PC pin termination. It is certified to UL standards and complies with RoHS directives, serving as a standard or medical-grade AC line filter.

Feature Summary

• Single-stage electromagnetic interference suppression
• Printed circuit board mounting configuration
• Medical-grade filter optimization capability

Applications

• PCB-mounted AC power input stages
• Medical equipment power supplies
• Standard electronic device EMC compliance

Procurement Notes

Verify the specific datasheet version for the 5500.2118 to confirm exact leakage current values and attenuation curves, as these parameters are critical for medical and sensitive applications. Ensure the selected variant matches the required voltage rating of 125 VAC or 250 VAC for the target system design.

Selection Notes

Select this component when a compact, single-stage solution is sufficient for low-current applications up to 2 A. It is appropriate for designs requiring PCB integration rather than chassis mounting. Consider the medical-grade certification if the end product requires compliance with stricter safety isolation standards.

Part Context

This part belongs to the Schurter 5500 series of EMI filters. Unlike higher-current chassis-mount variants in the same family, this model is optimized for printed circuit board installation. It provides essential noise reduction for single-phase AC lines in space-constrained electronic assemblies.

Replacement Considerations

Cross-reference with Schurter 5500.2119 for potential alternative specifications within the same series. Verify that any substitute maintains the 2 A current rating and single-stage topology to ensure compatibility with the existing PCB layout.
