B82725V2123U040

Overview

The B82725V2123U040 is a current-compensated ring core double choke designed for power line applications. It features a nominal inductance of 3.6 mH and supports a rated current of 12 A. The component operates within an ambient temperature range of -40°C to +125°C, including self-temperature rise effects. It is rated for 250 V AC and utilizes a vertical through-hole mounting configuration with four pins.

Feature Summary

• Current-compensated ring core design for effective common mode noise suppression
• Vertical through-hole construction for secure PCB integration
• High thermal stability suitable for demanding industrial environments

Applications

• Power line filtering in industrial electronics
• Electromagnetic compatibility (EMC) suppression in AC power inputs
• Noise reduction in equipment operating at 250 V AC

Procurement Notes

Verify the specific suffix U040 against official TDK/EPCOS documentation to confirm pin spacing and mechanical dimensions. Ensure the selected variant matches the required 3.6 mH inductance and 12 A current rating for your circuit design. Cross-reference datasheets for precise thermal derating curves and safety certifications before finalizing procurement.

Selection Notes

Select this component when a vertical form factor is required for space-constrained PCB layouts. The 12 A current rating makes it suitable for higher-power AC line applications compared to lower-current variants. Consider the 250 V AC rating to ensure compliance with local electrical safety standards for the target installation environment.

Part Context

This part belongs to the B82725 series of power line chokes from EPCOS/TDK. These components are engineered for robust electromagnetic interference suppression in AC power circuits. The series offers various inductance values and current ratings to accommodate diverse filtering requirements across industrial and consumer electronic systems.

Replacement Considerations

Check for direct substitutes within the B82725 family that share identical mechanical dimensions and electrical parameters. Verify that any alternative maintains the same 3.6 mH inductance and 12 A current handling capability while fitting the vertical 4-pin footprint.
