B82725S2602N041

Overview

The B82725S2602N041 is a current-compensated ring core double choke manufactured by EPCOS (TDK Electronics). It features an inductance of 7.8 mH at 10 kHz and supports a rated current of 6 A with a typical DC resistance of 24 mOhm. The component operates within a temperature range of -40 °C to +125 °C, with a rated operating temperature of +60 °C or +70 °C depending on the specific application context. It withstands a test voltage of 1500 V AC / 2100 V DC for 2 seconds between lines. Physical dimensions include a maximum length of 40.40 mm, width of 20.50 mm, and height of 37 mm.

Feature Summary

• Current-compensated ring core design for effective common mode noise suppression
• High current handling capability suitable for power line applications
• Robust insulation performance with high dielectric strength ratings

Applications

• Power supply input filtering
• Industrial equipment EMI suppression
• Consumer electronics power line protection

Procurement Notes

Verify the specific rated temperature (+60 °C or +70 °C) required for your thermal environment against the official datasheet. Confirm that the 6 A rated current aligns with your circuit's peak load requirements. Ensure the through-hole footprint matches your PCB layout constraints. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when high inductance values are needed for low-frequency noise attenuation in dual-line configurations. The 7.8 mH value provides significant impedance at 10 kHz. Consider the physical size constraints as the radial leaded package requires adequate board space. Evaluate the DC resistance impact on voltage drop if efficiency is critical in the power path.
