ESC-03-222-D

Power Line Filter Modules Overview

The ESC-03-222-D is a single-phase EMI/EMC power line filter from the Cosel ES series, rated for 3 A current and 250 VAC/VDC. It features screwless termination and chassis mounting. Key electrical parameters include a capacitance of 2200 pF, leakage current of 250 uA, and an operating frequency range of 150 kHz to 1 MHz. The unit complies with UL, CSA, DIN, and ENEC standards.

Power Line Filter Modules Feature Summary

• Provides common mode noise suppression for single-phase AC or DC circuits
• Utilizes screwless terminal connections for simplified installation
• Designed for direct chassis mounting applications

Power Line Filter Modules Applications

• Industrial control systems requiring EMI mitigation
• Medical equipment power input stages
• Information technology equipment (ITE) power conditioning

Power Line Filter Modules Procurement Notes

Verify the specific suffix 'D' against official Cosel documentation to confirm it denotes the correct terminal configuration or compliance variant. Ensure the required certification marks align with regional regulatory requirements before finalizing procurement orders.

Power Line Filter Modules Selection Notes

Select this component when a 3 A rating and screwless connection are required for chassis-mounted EMI filtering. Compare leakage current specifications against sensitive medical or audio applications. Confirm that the 2200 pF capacitance value meets system ground fault safety limits.

Power Line Filter Modules Part Context

This model belongs to the Cosel ES series of power line filters. It shares the same base electrical ratings as the ESC-03-222 but includes the '-D' suffix, which typically indicates a specific packaging, terminal style, or certification variation within the manufacturer's product lineup.

Power Line Filter Modules Replacement Considerations

The ESC-03-222 is the base model without the suffix. Verify if the '-D' designation implies a distinct physical dimension or certification requirement compared to the standard ESC-03-222 before substitution.
