B85321A2205A201

Overview

The B85321A2205A201 is a feed-through capacitor from the TDK B85321 series, designed for electromagnetic interference suppression. It features a capacitance of 1.0 μF with a ±20% tolerance. The component supports a rated AC voltage of 250 V and a DC voltage of 600 V. It has a maximum rated current of 200 A at 40 °C. Operating temperature ranges from -40 °C to 85 °C. The unit utilizes bolt mount installation with axial threaded terminals.

Feature Summary

• Provides effective electromagnetic interference suppression in power lines and signal circuits
• Utilizes screw mounting type for secure mechanical attachment
• Features axial threaded terminals for direct connection integration

Applications

• Electromagnetic interference suppression in power lines
• Signal line filtering applications
• Industrial electronic equipment noise reduction

Procurement Notes

Verify the specific manufacturer designation, as this part originates from EPCOS which was renamed to TDK Electronics. Confirm that the suffix 'A201' corresponds to the required terminal configuration and packaging. Ensure compatibility with the intended thermal environment, noting the 40 °C reference for rated current specifications.

Selection Notes

Select this component when high-current handling capability up to 200 A is required alongside significant capacitance for low-frequency filtering. The bolt-mount design suits heavy-duty industrial environments where vibration resistance is critical. Consider the physical dimensions of 55.00 mm diameter and 100.00 mm length during layout planning.

Part Context

This component belongs to the B85321 series of feed-through capacitors manufactured by TDK Electronics (formerly EPCOS). The series is engineered for robust performance in demanding electrical systems. These components are widely utilized in sectors requiring reliable noise suppression and stable operation under varying thermal conditions.

Replacement Considerations

Cross-reference with other B85321 series variants if different capacitance or voltage ratings are needed. Verify that substitute parts maintain the same axial threaded terminal style and bolt-mount footprint to ensure mechanical compatibility without redesigning the enclosure.
