B82734W2462B030

Overview

The B82734W2462B030 is a current-compensated D-core double choke manufactured by EPCOS (TDK Electronics). It features a nominal inductance of 4.6 mH and supports a maximum rated current of 4.6 A at +60 °C. The component has a typical DC resistance of 46 mΩ and an AC voltage rating of 250 V. It operates within a temperature range of -40 °C to +125 °C and holds ENEC, UR, and VDE approvals.

Feature Summary

• Current-compensated design for efficient magnetic field utilization
• D-core ferrite construction for high saturation performance
• Dual-winding configuration for balanced current handling

Applications

• Power factor correction circuits
• Switch-mode power supply input filtering
• Industrial motor drive chokes

Procurement Notes

Verify the specific suffix 'B030' against official TDK/EPCOS documentation to confirm lead-free compliance and packaging details. Ensure the application environment does not exceed the +60 °C ambient limit for the 4.6 A rating. Cross-reference approval agency marks (ENEC, UR, VDE) with regional regulatory requirements before integration.

Selection Notes

Select this component when dual-channel current compensation is required for noise suppression. Compare thermal derating curves against expected load profiles. Verify footprint compatibility with PCB layout constraints. Consider alternative inductance values if circuit impedance matching differs from standard 4.6 mH requirements.

Part Context

Part of the B82734 series of current-compensated double chokes. This series utilizes D-core ferrite technology to minimize electromagnetic interference in power electronics. The product line is designed for robust industrial and automotive applications requiring high current density and stable inductance under load.

Replacement Considerations

Check for direct cross-references in TDK's replacement matrix. Generic equivalents may lack specific approval certifications or identical thermal characteristics.
