B82734R2142B030

Overview

The B82734R2142B030 is a current-compensated D-core double choke manufactured by EPCOS (TDK Electronics). It is designed for power line applications with a rated voltage of 250 V AC. The component features a nominal inductance of 39 mH and a rated current capacity of 1.4 A at +40 °C or +60 °C. Constructed with a ferrite core, it provides effective common mode filtering for electronic circuits requiring stable switching characteristics and reliable thermal behavior in high-power environments.

Feature Summary

• Current-compensated double choke design for efficient common mode noise suppression
• D-core construction utilizing ferrite material for enhanced magnetic performance
• Rated for 250 V AC operation suitable for standard power line integration

Applications

• High-power motor control cabinets
• Power line filtering systems
• Industrial electronic equipment requiring electromagnetic interference reduction

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required current ratings and inductance tolerances. Confirm that the rated voltage and current specifications align with the target circuit's operational parameters. Check for RoHS compliance status if environmental regulations apply to the assembly process. Ensure the physical dimensions fit the designated PCB layout or mounting space within the enclosure.

Selection Notes

Select this component when a current-compensated topology is required to minimize DC resistance while maintaining high common mode impedance. The D-core form factor offers a balance between inductance density and thermal stability. Consider the 1.4 A rated current limit when designing for continuous load conditions. Verify that the 39 mH inductance value meets the specific frequency attenuation requirements of the application.

Part Context

This part belongs to the B82734 series of chokes for power lines produced by EPCOS, now integrated into TDK Electronics. The series encompasses various inductance values and current ratings tailored for different power line filtering needs. These components are widely used in industrial and consumer electronics to mitigate electromagnetic interference generated by switching power supplies and motor drives.

Replacement Considerations

Direct substitutes include other parts from the B82734 series with matching inductance and current ratings, such as B82734R2132B030 variants. Cross-reference electrical parameters like nominal inductance and rated current before substitution. Physical footprint compatibility must be verified for direct replacement scenarios.
