EAP-03-221-D

Power Line Filter Modules Overview

The EAP-03-221-D is a single-phase EMI/EMC power line filter manufactured by Cosel USA, Inc. It supports voltage ratings of 250 VAC and 250 VDC with a current rating of 3 A. The unit features chassis mount installation and screw termination. Key electrical parameters include a leakage current of 37.5 uA and a capacitance of 330 pF. It belongs to the EA series and holds UL, CSA, DIN, and ENEC compliance certifications.

Power Line Filter Modules Feature Summary

• Provides common mode noise filtering for AC and DC power lines
• Designed for secure chassis mounting applications
• Utilizes screw termination for reliable electrical connections

Power Line Filter Modules Applications

• Industrial control panels requiring EMI suppression
• Medical equipment power input stages
• Test and measurement instrumentation

Power Line Filter Modules Procurement Notes

Verify the specific suffix D against official Cosel documentation to confirm terminal type and mounting configuration. Ensure the application environment matches the 250 VAC/VDC rating and 3 A current limit. Confirm that the 37.5 uA leakage current complies with safety standards for the intended end-use device. Cross-reference the EA series datasheet for thermal derating curves if operating near rated limits.

Power Line Filter Modules Selection Notes

Select this component when a low-capacitance filter is required to minimize leakage current in sensitive applications. The 330 pF value offers a balance between noise attenuation and safety compliance. Compare with the ESP-03-221-D if DIN rail mounting is preferred over chassis mounting. Ensure the enclosure design accommodates the physical dimensions specified in the mechanical drawings.

Power Line Filter Modules Part Context

This model is part of the Cosel EA series, which focuses on compact power line filters for general industrial use. It shares the same electrical specifications as other variants in the series but differs in mounting style and termination method. The product is designed to meet international electromagnetic compatibility standards for electronic equipment.

Power Line Filter Modules Replacement Considerations

The ESP-03-221-D is a functional alternative within the same manufacturer lineup, offering identical electrical performance but utilizing DIN rail mounting instead of chassis mount. Verify mechanical fit and terminal accessibility before substitution.
