Overview
The B82747E6253A040 is a current-compensated ring core triple choke manufactured by EPCOS (TDK). It features a 1 mH inductance at 100 kHz and supports a rated current of 25 A. The typical DC resistance is 2.8 mΩ. Designed for through-hole mounting, the component has a cylindrical construction with ferrite core material. Physical dimensions include a diameter of 65.00 mm and a width of 37.00 mm. It operates within a temperature range of -40 °C to +125 °C.
Feature Summary
- Current-compensated ring core design for triple chokes
- High current handling capability of 25 A
- Low DC resistance for efficient power transmission
- Through-hole mounting for robust mechanical stability
Applications
- Three-phase power line filtering
- Industrial motor drive systems
- Uninterruptible power supply (UPS) units
Procurement Notes
Verify the specific suffix 'A040' against the official TDK datasheet to confirm exact tolerance and packaging specifications. Ensure the procurement channel provides original manufacturer documentation. Cross-reference the RoHS compliance status with the latest regulatory updates. Confirm that the through-hole lead dimensions match the target PCB layout requirements before finalizing orders.
Selection Notes
Select this component when high common-mode rejection is required in three-phase applications. The 1 mH inductance value suits standard power line frequencies. Consider the 25 A current rating to ensure adequate headroom for peak loads. The through-hole package offers superior mechanical strength compared to surface-mount alternatives in high-vibration environments.
Part Context
This part belongs to the B82747 series of current-compensated ring core chokes from EPCOS (TDK). These components are engineered for demanding power electronics applications where size and efficiency are critical. The series utilizes advanced ferrite materials to minimize losses while maintaining high magnetic performance under heavy load conditions.
Replacement Considerations
Consult the official TDK replacement guide for direct equivalents. Verify pin compatibility and inductance tolerances before substituting. Ensure thermal characteristics match the original design constraints.
