B85321A2405A201

Overview

The B85321A2405A201 is an EMI feedthrough filter manufactured by TDK under the EPCOS brand. It features a rated voltage of 250 V AC (50/60 Hz) and 600 V DC. The component is designed for electromagnetic interference suppression in electronic circuits. It operates within a temperature range up to +85°C and is supplied in bulk packaging.

Feature Summary

• Provides effective electromagnetic interference suppression through feedthrough filtering technology
• Supports high DC voltage ratings suitable for robust power line applications
• Constructed as a passive component for reliable noise reduction

Applications

• EMI suppression in power supply lines
• Electromagnetic compatibility enhancement in industrial equipment
• Noise filtering in sensitive electronic circuitry

Procurement Notes

Verify the specific suffix code to ensure correct voltage and current ratings, as variations exist within the B85321 series. Confirm package type and lead configuration match design requirements. Check RoHS compliance status if required by project specifications. Ensure handling procedures account for electrostatic discharge sensitivity during installation.

Selection Notes

Select this component when high DC voltage blocking capability is required alongside AC line filtering. Consider the rated current limits at operating temperatures. Evaluate space constraints due to feedthrough form factor. Compare performance against standard capacitors if higher frequency attenuation is needed.

Part Context

This part belongs to the B85321 series of feedthrough filters from TDK/EPCOS. These components are engineered for direct mounting on panel holes or chassis connections. They serve as critical elements in meeting regulatory EMC standards for conducted emissions.

Replacement Considerations

Check datasheets for alternative parts with matching 600V DC rating and similar physical dimensions. Verify that substitute components offer comparable insertion loss characteristics at target frequencies.
