B82730G3951A020

Overview

The B82730G3951A020 is a current-compensated U-core double choke designed for power line applications. It features a rated inductance of 2.2 mH and supports a maximum rated current of 950 mA. The component operates within a temperature range of -40°C to +125°C, including self-temperature rise effects. It utilizes a horizontal package with four PC pins for through-hole mounting. The device has a maximum height of 12.00 mm and is rated for 300 V AC.

Feature Summary

• Current-compensated U-core design for effective common mode noise suppression
• Horizontal through-hole mounting configuration with four pins
• Rated for high operating temperatures up to 125°C

Applications

• Power line filtering in electronic equipment
• Common mode interference suppression in industrial electronics
• EMI reduction in consumer information technology devices

Procurement Notes

Verify the specific ordering suffix against official TDK EPCOS documentation to ensure correct inductance and current ratings. Confirm that the horizontal pin configuration matches your PCB layout requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure the 300V AC voltage rating meets your circuit's safety isolation needs. Cross-reference the datasheet version date to confirm the most recent technical specifications are applied.

Selection Notes

Select this component when a compact U-core choke is needed for moderate current levels around 950 mA. The horizontal package facilitates specific board orientations where vertical height is constrained but length is available. Consider the 2.2 mH inductance value for the target frequency range of interference suppression. Verify that the through-hole mounting method aligns with your assembly process capabilities and mechanical stress requirements.

Part Context

This part belongs to the B82730 series of current-compensated chokes from TDK EPCOS. These components are engineered for robust performance in demanding environments. The series offers various inductance and current combinations to suit different power line filtering needs.
