B82730G3162A020

Overview

The B82730G3162A020 is a current-compensated U-core double choke manufactured by TDK. It features an inductance of 1 mH with a tolerance range of -30% to +50%. The component supports a maximum DC current of 1.6 A and has a maximum DC resistance of 160 mOhms. Designed for horizontal mounting via radial leads, it operates within a temperature range of -40°C to +125°C. The ferrite core construction ensures effective common mode filtering for power line applications.

Feature Summary

• Current-compensated design utilizing a U-core structure for efficient magnetic field cancellation.
• Radial leaded configuration suitable for through-hole horizontal mounting on printed circuit boards.
• Ferrite core material provides stable performance across a wide operating temperature range.

Applications

• Power line EMI suppression in electronic equipment
• Common mode noise filtering in AC/DC power supplies
• Signal integrity protection in industrial control systems

Procurement Notes

Verify the specific suffix code against official TDK documentation to confirm exact electrical tolerances and packaging details. Ensure compatibility with existing board layouts regarding vertical clearance and lead spacing. Cross-reference RoHS compliance status directly with the manufacturer's latest product specification sheet before finalizing procurement orders.

Selection Notes

Select this component when a 1 mH inductance value is required for common mode noise reduction in low-current power lines. The 1.6 A current rating suits applications where space constraints favor a compact U-core form factor over larger frame cores. Verify that the -30% to +50% tolerance aligns with the system's electromagnetic interference mitigation requirements.

Part Context

This part belongs to the B82730G series of power line chokes from TDK Electronics. The series offers various inductance values tailored for different current ratings and voltage levels. These components are widely used in consumer electronics and industrial machinery to meet regulatory emissions standards while maintaining signal integrity in power delivery networks.

Replacement Considerations

Check the B82730U series for potential mechanical or electrical equivalents. Confirm that substitute parts match the 1 mH inductance, 1.6 A current rating, and 160 mOhm DC resistance specifications. Verify footprint compatibility and thermal performance characteristics before implementing any alternative sourcing strategies.
