EAP-03-331

Power Line Filter Modules Overview

The Cosel EAP-03-331 is a single-phase EMI/EMC power line filter designed for chassis mounting. It supports voltage ratings of 250 VAC and 250 VDC with a current rating of 3 A. The unit features screw termination and includes a capacitance of 330 pF. Leakage current is specified at 37.5 uA. It holds UL, CSA, DIN, and ENEC compliance certifications.

Power Line Filter Modules Feature Summary

• Provides common mode noise filtering for single-phase AC or DC circuits
• Designed for secure chassis mounting using screw terminals
• Certified to meet international safety standards including UL, CSA, DIN, and ENEC

Power Line Filter Modules Applications

• Industrial control systems requiring EMI suppression
• Medical equipment power input stages
• General purpose electronic devices needing EMC compliance

Power Line Filter Modules Procurement Notes

Verify the specific suffix designation when ordering, as variants such as EAP-03-331-D may indicate different mounting styles like DIN rail instead of chassis mount. Confirm terminal type and leakage current requirements against the official datasheet to ensure compatibility with sensitive load applications. Check certification marks required by your target market before finalizing procurement.

Power Line Filter Modules Selection Notes

Select this component for low-current applications up to 3 A where minimal leakage current is critical. Ensure the enclosure allows for direct chassis mounting. Compare against the EAP-03-332 if higher capacitance or different leakage characteristics are needed. Verify that the operating temperature range meets system environmental specifications.

Power Line Filter Modules Part Context

This part belongs to the Cosel EA series of power line filters. The series offers various current ratings and capacitance values to suit different electromagnetic interference suppression needs. The EAP-03-331 represents the lower current end of the spectrum within this product family.

Power Line Filter Modules Replacement Considerations

Direct substitutes include other Cosel models from the EA series with matching 3 A ratings. Cross-reference electrical parameters carefully, particularly leakage current and capacitance values, to maintain circuit stability and regulatory compliance.
