B85321A2204A250

Overview

The B85321A2204A250 is a feed-through capacitor from the B85321 series manufactured by EPCOS - TDK Electronics. It features a bulk package and is designed for electromagnetic interference suppression. The component has a rated voltage of 250 V AC (50/60 Hz) or 600 V DC. Rated current specifications are defined relative to a 40 °C rated temperature, with reduced current values applicable at 400 Hz.

Feature Summary

• Feed-through capacitor design for effective electromagnetic interference filtering
• Capable of handling high DC voltage ratings alongside standard AC line frequencies

Applications

• Electromagnetic interference suppression in electronic circuits
• Power supply input filtering applications

Procurement Notes

Verify the specific datasheet version for the B85321A2204A250 to confirm current manufacturing status and detailed mechanical dimensions. Ensure that thermal management strategies account for the rated current limits at 40 °C, particularly if operating conditions involve higher ambient temperatures or frequencies around 400 Hz where current ratings may be reduced.

Selection Notes

Select this component when a robust feed-through capacitor solution is required for EMI filtering in power lines. Consider the 600 V DC rating for appropriate voltage headroom. Evaluate the thermal environment carefully, as the rated current is specified at 40 °C, and derating may be necessary for higher temperature operations or specific frequency ranges like 400 Hz.
