B85121A2205A630

Overview

The B85121A2205A630 is a feedthrough capacitor from the TDK B85121 series, designed for high-performance electromagnetic interference (EMI) suppression. It features a capacitance of 2 µF and a rated voltage of 600V DC. The component supports a maximum DC current of 63 A and delivers an insertion loss of 90 dB at 100 MHz. Housed in an axial package with M8 threaded terminals, it measures 55.00 mm in diameter and 60.00 mm in length. It operates within a temperature range of -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Provides high attenuation of electromagnetic interference with 90 dB insertion loss at 100 MHz
• Supports high continuous DC current loads up to 63 A
• Features robust mechanical construction with M8 threaded terminal connections
• Designed for reliable operation across a wide industrial temperature range

Applications

• Power supply input filtering for industrial equipment
• EMI suppression in high-current DC power distribution systems
• Filtering applications requiring high voltage isolation and current handling

Procurement Notes

Verify part authenticity through authorized TDK distributors due to obsolete status. Confirm RoHS3 compliance and specific lot codes if required by regulatory standards. Check for alternative sourcing options as original manufacturing may be discontinued. Ensure storage conditions maintain component integrity prior to installation.

Selection Notes

Select this component for applications requiring high capacitance and current handling in a compact axial form factor. Consider the M8 threading for secure mounting in vibration-prone environments. Evaluate thermal management needs given the 63 A current rating and operating temperature limits.

Part Context

This component belongs to the TDK B85121 series of feedthrough capacitors, formerly marketed under the EPCOS brand. These components are engineered for demanding EMI filtering tasks where space constraints and high performance are critical. The series utilizes advanced ceramic dielectric materials to achieve stable electrical characteristics over time and temperature variations.
