B82734W2701B030

Overview

The EPCOS B82734W2701B030 is a double choke designed for power line filtering, featuring a current-compensated D core construction. It provides an inductance of 68 mH with a maximum rated current of 700 mA and a rated voltage of 250 VAC. The component utilizes radial leaded termination for through-hole mounting within a rectangular package. It operates reliably across a temperature range from -40 °C to +125 °C and complies with RoHS standards.

Feature Summary

• Current-compensated D core design for effective common mode noise suppression
• Radial leaded configuration suitable for through-hole PCB mounting
• High thermal stability supporting operation up to 125 °C

Applications

• Power line filtering in electronic equipment
• Electromagnetic compatibility (EMC) improvement circuits
• Common mode noise suppression in AC power inputs

Procurement Notes

Verify the specific manufacturer source, as EPCOS components are now integrated into TDK Electronics. Confirm that the part number matches the exact 68 mH specification and 700 mA rating. Ensure compliance with current environmental regulations such as RoHS. Check for any updated datasheets or pinout diagrams to guarantee correct integration into the target circuit design.

Selection Notes

Select this component when a high-inductance common mode choke is required for low-current AC applications. The 68 mH value targets significant noise attenuation at lower frequencies. The 700 mA current rating limits suitability to smaller power stages. Consider the physical dimensions and through-hole mounting requirements during layout planning.

Part Context

This component belongs to the B82734W series of EMC power chokes manufactured by EPCOS, now part of TDK. This series is characterized by its D core geometry and radial leaded form factor. These chokes are engineered specifically for suppressing electromagnetic interference in power supply lines, offering a compact solution for maintaining signal integrity in noisy environments.
