B84112G0000G120

Power Line Filter Modules Overview

The EPCOS B84112G0000G120 is a single-phase EMC power line filter designed for enhanced insertion loss. It features a rated current of 20 A and a rated voltage of 250 V AC/DC, operating at 50 Hz or 60 Hz. The unit utilizes a metal case with polyurethane potting (UL 94 V-0) and employs M5 threaded posts for panel mounting. Key electrical parameters include a maximum leakage current of 0.369 mA, withstand voltages of DC 1770 V (line-to-line) and AC 2500 V (line-to-case), and dimensions of approximately 125 mm length, 84 mm depth, and 38.1 mm height.

Power Line Filter Modules Feature Summary

• Enhanced insertion loss performance for effective interference suppression
• Robust metal housing construction with UL 94 V-0 polyurethane potting
• Low leakage current design suitable for sensitive equipment connections

Power Line Filter Modules Applications

• Industrial machinery electromagnetic compatibility protection
• Power supply input filtering for electronic devices
• Equipment requiring strict adherence to emission standards

Power Line Filter Modules Procurement Notes

Verify the specific suffix G120 against official TDK/EPCOS documentation to confirm terminal type and mechanical specifications. Ensure the application environment remains within the -25°C to +85°C operating temperature range. Confirm that the 20 A continuous current rating aligns with the system's peak load requirements without exceeding thermal limits defined in the datasheet.

Power Line Filter Modules Selection Notes

Select this component when enhanced attenuation is required compared to standard series filters. The 20 A current capacity supports high-power single-phase applications. Verify that the M5 threaded post installation method fits the chassis design constraints. Consider the low leakage current specification if safety isolation is critical for the connected load.

Power Line Filter Modules Part Context

This component belongs to the SIFI-G series of single-phase EMI filters manufactured by EPCOS, now part of TDK Electronics. The series is characterized by its metal case construction and polyurethane potting, providing durability and consistent performance in industrial environments. It serves as an interference suppression solution for AC power lines.

Power Line Filter Modules Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic replacements may not match the enhanced insertion loss characteristics or the specific M5 threaded post mounting configuration of the original component.
