B85121A2104A750

Overview

The B85121A2104A750 is a feedthrough capacitor manufactured by EPCOS - TDK Electronics. It features a capacitance of 0.1 µF with a tolerance of ±20%. The component has a rated operating voltage of 600V and supports a maximum current flow of 75 A. The physical connection utilizes an M6 thread size.

Feature Summary

• Provides electromagnetic interference suppression through feedthrough capacitor design
• Supports high current handling capability for power line applications
• Utilizes threaded mounting interface for secure installation

Applications

• EMI/RFI filtering in electronic circuits
• Power supply input stages requiring high current capacity
• Industrial equipment noise suppression

Procurement Notes

Verify the specific datasheet version to confirm mechanical dimensions and terminal configurations. Ensure the application environment does not exceed the 600V rating or 75A current limit. Confirm that the M6 thread size matches the panel cutout requirements. Cross-reference the manufacturer part number to avoid counterfeit components.

Selection Notes

Select this component when a feedthrough topology is required for superior high-frequency attenuation compared to standard capacitors. The 75A current rating makes it suitable for main power lines rather than signal lines. Verify that the 0.1 µF capacitance value aligns with the target frequency range for noise suppression in the specific circuit design.

Part Context

This component belongs to the EPCOS feedthrough capacitor series, designed for robust electromagnetic compatibility. Feedthrough capacitors offer lower parasitic inductance than traditional leaded capacitors, making them effective for high-frequency noise elimination in demanding industrial and automotive environments.

Replacement Considerations

Consult official substitution lists for equivalent feedthrough capacitors with matching M6 threading, 0.1 µF capacitance, and 75A current ratings. Verify that any substitute maintains the same voltage rating and mechanical footprint to ensure compatibility with existing panel mounts.
