RSEL-2003W

Power Line Filter Modules Overview

The TDK-Lambda RSEL-2003W is a single-phase EMC/EMI power line filter designed for AC and DC circuits. It features a rated voltage of 250VAC and 250VDC, with a nominal current capacity of 3A. The unit provides high insulation resistance of at least 100MΩ and withstands AC 2500V between terminals and chassis. It utilizes a wire terminal interface and is constructed for chassis mounting. The filter supports UL 1283 and CSA C22.2 No.8 certifications, ensuring compliance with international safety standards for electronic equipment noise suppression.

Power Line Filter Modules Feature Summary

• Single-stage EMI/EMC filtering architecture for effective noise attenuation
• Low-leakage current design suitable for sensitive medical and industrial applications
• Robust insulation performance with high dielectric withstand voltage
• Chassis mount construction with wire terminal connections

Power Line Filter Modules Applications

• Medical equipment requiring low leakage current compliance
• Industrial control units needing robust EMI suppression
• General purpose AC/DC power supply input filtering

Power Line Filter Modules Procurement Notes

Verify the specific ordering suffix to ensure correct terminal configuration and certification requirements. Confirm that the application environment does not exceed the rated temperature derating limits above 55°C. Ensure compatibility with existing chassis mounting hardware and wire gauge specifications before integration into the final assembly.

Power Line Filter Modules Selection Notes

Select this component when a single-phase filter with a 3A rating is required for both AC and DC lines. Consider the low leakage current specification if the application involves patient-connected or highly sensitive analog circuits. Verify that the physical dimensions and chassis mounting style fit within the available enclosure space constraints.

Power Line Filter Modules Part Context

This component belongs to the RSEL series of power line filters from TDK-Lambda. The series offers various current ratings and configurations for different power levels. The RSEL-2003W specifically addresses mid-range power applications requiring reliable noise suppression in compact form factors while maintaining strict safety isolation standards.

Power Line Filter Modules Replacement Considerations

Direct substitutes include other models within the TDK-Lambda RSEL series with matching electrical ratings. Cross-brand replacements must match the 3A current, 250VAC/DC voltage, and chassis mounting footprint. Verify that any alternative maintains equivalent leakage current and insulation withstand capabilities.
