B82724J8162N040

Overview

The B82724J8162N040 is a current-compensated ring core double choke from the B82724J8 series. It features an inductance of 47 mH per line with a rated current of 1.6 A. The component supports a rated voltage of 250 V AC (50/60 Hz) and 800 V DC, with a test voltage of 2000 V AC for 2 seconds between lines. Rated temperature is +70 °C. It utilizes through-hole mounting in a horizontal configuration.

Feature Summary

• Current-compensated ring core design for power line filtering
• Dual-line configuration for common mode noise suppression
• High insulation strength with 2000 V AC line-to-line test voltage

Applications

• Power line EMI filtering
• Industrial electronic equipment input stages
• Automotive electronics power supplies

Procurement Notes

Verify the specific suffix N040 against the manufacturer's latest datasheet to confirm package orientation and terminal plating specifications. Ensure the rated temperature of +70 °C aligns with the thermal requirements of the target application environment. Cross-reference the part number with TDK Electronics official documentation to confirm availability and any recent brand transition updates following the merger with EPCOS.

Selection Notes

Select this component when high inductance (47 mH) is required for effective low-frequency noise attenuation in dual-line power circuits. The 1.6 A rated current capacity suits moderate power applications. Verify that the horizontal mounting style fits the PCB layout constraints and that the +70 °C operating limit meets the system's thermal profile without requiring additional cooling measures.

Part Context

This component belongs to the B82724J8 series of current-compensated ring core chokes manufactured by TDK Electronics. These components are designed for power line filtering applications where high common mode impedance is necessary. The series offers various inductance values and current ratings to accommodate different power supply requirements in industrial and automotive sectors.

Replacement Considerations

Consult TDK Electronics official substitution guides for equivalent parts within the B82724J series or compatible ring core chokes with matching 47 mH inductance and 1.6 A current rating. Verify pin compatibility and thermal characteristics before substituting.
