B82725J2602N020

Overview

The B82725J2602N020 is a current-compensated ring core double choke from the EPCOS (TDK) B82725A series, designed for power line applications. It features an inductance of 3.9 mH at 10 kHz and supports a rated current of 6 A with a typical DC resistance of 30 mOhm. The component utilizes a horizontal through-hole mounting configuration with four pins, measuring 44.00 mm in length, 42.40 mm in width, and 25.00 mm in maximum height. It operates reliably within a temperature range of -40°C to +125°C.

Feature Summary

• Current-compensated ring core design for effective common mode noise suppression
• Dual-line filtering capability for AC power line protection
• Robust horizontal through-hole construction for secure mechanical mounting

Applications

• Power line filtering in industrial electronics
• EMI suppression in automotive electronic systems

Procurement Notes

Verify the specific ordering suffix against official TDK documentation to ensure correct electrical characteristics and packaging. Confirm that the component meets RoHS compliance requirements for your region. Cross-reference the manufacturer part number with the latest datasheet to validate pinout and dimensional tolerances before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring high-current common mode chokes with significant inductance values. Ensure the operating environment stays within the specified -40°C to +125°C range. Verify that the PCB layout accommodates the horizontal package dimensions and that the thermal management strategy supports the self-heating effects associated with 6 A continuous current operation.

Part Context

This component belongs to the B82725A/J series of power line chokes manufactured by EPCOS, now integrated into TDK Electronics. The series offers various inductance and current ratings tailored for different power line filtering needs. These chokes are widely used in applications demanding reliable electromagnetic interference mitigation in harsh environments.

Replacement Considerations

Consult official TDK substitution lists for direct replacements. Ensure any alternative part matches the 3.9 mH inductance, 6 A current rating, and horizontal through-hole form factor. Verify compatibility with existing PCB footprints and thermal constraints.
