B82722J2301N002

Overview

The B82722J2301N002 is a current-compensated ring core double choke manufactured by EPCOS (TDK Electronics). It features a nominal inductance of 68 mH measured at 10 kHz and supports a maximum rated current of 300 mA. The component utilizes a ferrite core material and is housed in a vertical through-hole package with four pins. It operates within a temperature range of -40 °C to +125 °C and is designed for 250 V AC power line applications.

Feature Summary

• Provides effective power line filtering through high inductance values suitable for noise suppression
• Utilizes a current-compensated ring core design for efficient magnetic field management
• Constructed with a robust ferrite core to ensure stable performance under varying conditions

Applications

• Power line filtering in electronic equipment
• Noise suppression in AC power circuits
• EMI reduction in general purpose power supplies

Procurement Notes

Verify the specific inductance tolerance and DC resistance requirements against the official datasheet before procurement. Confirm that the 300 mA current rating aligns with the application's peak load demands. Ensure the vertical through-hole mounting style fits the PCB layout constraints. Check RoHS compliance status if environmental regulations are strict for the target market.

Selection Notes

Select this component when a 68 mH inductance is required for low-frequency noise attenuation in 250 V AC systems. Consider the 300 mA current limit to prevent saturation during normal operation. Evaluate the physical dimensions of the vertical package to ensure adequate clearance on the circuit board. Compare thermal characteristics to ensure reliable operation within the specified -40 °C to +125 °C range.

Part Context

This part belongs to the B82722 series of power line chokes, which are current-compensated ring core double chokes designed for 250 V AC applications. The series offers various inductance values ranging from 1.2 mH to 68 mH with different current ratings. These components are widely used in industrial and consumer electronics for electromagnetic interference suppression.

Replacement Considerations

Compatible substitutes include other B82722 series variants such as B82722J2301N001 or B82722A2301N002, provided their electrical parameters match the system requirements. Verify pin configuration and mechanical dimensions to ensure interchangeability without PCB modifications.
