B82732F2901B001

Overview

The B82732F2901B001 is a current-compensated frame core double choke designed for power line applications. It provides common mode filtering with an inductance of 27 mH and a rated current of 0.9 A. The component operates at 250 V AC and features through-hole mounting. Its physical dimensions are 24.5 mm in length, 14.5 mm in width, and 13.5 mm in height. The device exhibits low resistance and high pulse-handling capability, making it suitable for symmetrical interference suppression.

Feature Summary

• Current-compensated frame core design for effective common mode noise reduction
• High inductance combined with low DC resistance for efficient signal transmission
• Approximately 2% stray inductance to ensure symmetrical interference suppression
• Robust construction supporting high pulse-handling capabilities

Applications

• Single phase EMI filtering in power supplies
• Noise suppression in household appliances
• Industrial automation equipment power lines
• Renewable energy system input stages

Procurement Notes

Verify the specific suffix B001 against the manufacturer's latest datasheet to confirm pinout and mechanical tolerances. Ensure the procurement channel provides original documentation from EPCOS or TDK Electronics. Cross-reference the UL and VDE certification marks on the component body with official safety databases. Confirm that the tin-plated terminals meet the required solderability standards for your assembly process.

Selection Notes

Select this component when a compact, current-compensated choke is required for single-phase AC lines up to 0.9 A. The 27 mH inductance offers significant attenuation for common mode noise while maintaining low differential mode impedance. Consider the radial leaded package for standard PCB mounting where space constraints allow for a 24.5 mm footprint. Evaluate the thermal performance under continuous load conditions to ensure compliance with the +40 °C operating temperature rating.

Part Context

This part belongs to the B82732F series of power line chokes manufactured by EPCOS, now part of TDK Electronics. The series utilizes a frame core technology to achieve high magnetic efficiency in a small volume. These components are specifically engineered for electromagnetic compatibility (EMC) in electronic devices connected to mains power. The design prioritizes low stray inductance to prevent differential mode conversion of common mode noise.

Replacement Considerations

Check for direct substitutes within the B82732F series with different inductance values if current requirements vary. Verify mechanical compatibility with existing PCB layouts before substituting with other frame core chokes. Ensure any replacement maintains the same voltage rating and certification status for regulatory compliance.
