Procurement Notes

Verify the specific datasheet version as this part number may be marked obsolete by the manufacturer. Confirm availability through authorized distributors or secondary markets if new production units are not listed. Ensure the M10 threading matches your panel thickness and mounting requirements. Check for equivalent newer series replacements within the EPCOS portfolio that offer updated specifications or improved availability while maintaining similar electrical characteristics.

Selection Notes

Select this component when high capacitance and high current ratings are required in a compact feed-through form factor. The 600V rating makes it suitable for medium-voltage DC applications. Consider the M10 terminal size for mechanical integration. Evaluate the 90dB attenuation at 100MHz against your specific EMI suppression needs. Ensure the -40°C to +85°C temperature range covers your operational environment.

Part Context

This component belongs to the EPCOS feed-through capacitor line, designed for robust EMI filtering in industrial and power electronics. These capacitors integrate the capacitor element directly into the conductive path, offering low impedance and high surge current tolerance. The B85121 series specifically targets applications requiring significant capacitance values in a rugged, threaded housing configuration.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the part status is listed as obsolete, consult the manufacturer's official replacement guide or contact technical support for direct cross-reference recommendations.
