ESC-03-102

Power Line Filter Modules Overview

The ESC-03-102 is a single-phase EMI/EMC power line filter manufactured by Cosel USA, Inc. It supports a voltage rating of 250 VAC and 250 VDC with a current capacity of 3 A. The unit features chassis mount installation and screwless termination. Key electrical parameters include a leakage current of 130 uA, a capacitance of 1 nF, and an operating frequency range of 150 kHz to 1 MHz. It holds UL, CSA, DIN, and ENEC compliance certifications.

Power Line Filter Modules Feature Summary

• Provides single-stage EMI/EMC filtering for single-phase power lines
• Utilizes screwless termination technology for secure connections
• Designed for direct chassis mounting applications

Power Line Filter Modules Applications

• Industrial equipment power conditioning
• Medical device power supply input stages
• Information Technology Equipment (ITE) noise suppression

Power Line Filter Modules Procurement Notes

Verify the specific suffix designation when ordering, as variants such as ESC-03-102-D exist with different mounting styles like DIN rail. Confirm that the required leakage current and capacitance values align with system safety and EMC requirements. Ensure the chassis mount form factor fits the intended enclosure design constraints before finalizing procurement.

Power Line Filter Modules Selection Notes

Select this component when a low-current, single-phase filter is required for chassis-mounted installations. Compare against the ESP series if DIN rail mounting is preferred instead of chassis mounting. Verify that the 3 A current rating meets the maximum load requirements of the downstream circuitry without derating issues.

Power Line Filter Modules Part Context

This model belongs to the ES series of power line filters from Cosel. It serves as a specialized component for electromagnetic interference suppression in AC and DC power inputs. The product is distinct from higher current variants within the same family, focusing on lower amperage applications requiring robust chassis integration.

Power Line Filter Modules Replacement Considerations

The ESC-03-102-D is a related variant within the same series but utilizes DIN rail mounting rather than chassis mounting. Ensure mechanical compatibility is maintained when substituting between these forms. No other direct cross-model replacements are confirmed in the provided documentation.
