B84111A0000A120

Power Line Filter Modules Overview

The B84111A0000A120 is a single-phase EMI power line filter from the SIFI-A series, manufactured by EPCOS (TDK). It features a metal case with polyurethane potting and is designed for chassis mounting. Rated for AC/DC 250V at 50/60Hz, it supports a rated current of 20A at 40°C. The unit utilizes 6.3x0.8mm tab terminals and provides an inductance of 430μH. Physical dimensions are 72mm x 46mm x 26mm with a net weight of 130g. It operates within a temperature range of -25°C to +100°C and has a maximum leakage current of 0.369mA.

Power Line Filter Modules Procurement Notes

Verify the specific suffix 'M120' against official TDK documentation to confirm terminal type and certification status. Ensure the application environment does not exceed the 100°C upper temperature limit. Confirm that the 20A rating aligns with the thermal conditions of the final assembly, as ratings are typically specified at 40°C.

Power Line Filter Modules Selection Notes

Select this component when a robust, high-current single-phase filter is required for chassis mounting. The metal enclosure offers superior mechanical protection compared to plastic alternatives. Verify that the 6.3mm tab terminals match the mating connector specifications. Consider the physical footprint constraints given the 72mm length.

Power Line Filter Modules Part Context

This component belongs to the SIFI-A series of single-phase EMI filters produced by EPCOS, now integrated into TDK Electronics. The series is characterized by metal cases and polyurethane potting for durability. These filters are engineered for mains frequency applications and provide essential noise suppression for electronic circuits connected to AC power lines.

Power Line Filter Modules Replacement Considerations

Consult official TDK cross-reference lists for verified substitutes. Generic equivalents may differ in leakage current or insulation voltage ratings. Ensure any replacement maintains the same tab terminal dimensions and mounting hole pattern.
