B84111F0000M120

Power Line Filter Modules Overview

The B84111F0000M120 is a single-phase EMI power line filter from the SIFI-A series, rated for AC/DC 250V and 20A at 40°C. It features a metal chassis with polyurethane potting (UL 94 V-0) and operates between -25°C and +100°C. Key electrical parameters include 430μH inductance, maximum 0.369mA leakage current, and dielectric withstand voltages of DC1770V (line-line) and AC2500V (line-case). Dimensions are 72mm x 46mm x 26mm, weighing 130g.

Power Line Filter Modules Feature Summary

• Metal case construction with polyurethane potting for mechanical stability and UL 94 V-0 flame rating
• Low leakage current design suitable for sensitive medical or safety-critical applications
• Chassis mounting configuration with tab terminals for secure installation

Power Line Filter Modules Applications

• Industrial equipment requiring single-phase EMI suppression
• Medical devices adhering to strict leakage current limits
• Power supplies and inverters needing robust thermal performance

Power Line Filter Modules Procurement Notes

Verify the specific suffix 'M120' against official TDK/EPCOS documentation to confirm low-leakage specifications and terminal type. Ensure the rated current of 20A aligns with your system's thermal environment, as ratings often derate above 40°C. Confirm compliance with required regional certifications such as UL or ENEC before finalizing procurement.

Power Line Filter Modules Selection Notes

Select this component when a single-stage filter is sufficient for noise attenuation requirements. The metal housing provides superior heat dissipation compared to plastic enclosures. Verify that the 6.3mm tab terminals match your wiring harness connectors. Consider the physical dimensions and chassis mounting holes during PCB or panel layout planning.

Power Line Filter Modules Part Context

This model belongs to the SIFI-A series of single-phase EMI filters manufactured by EPCOS (TDK Electronics). The series offers various current ratings from 1A to 20A within identical form factors. These filters are designed for direct chassis mounting, providing a compact solution for electromagnetic interference suppression in standard 50/60Hz power lines.

Power Line Filter Modules Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic replacements may differ in leakage current, inductance values, or certification status. Ensure any alternative part matches the 20A rating and chassis mounting dimensions to maintain mechanical compatibility.
