Overview
The B82747E6353A040 is a radial leaded ferrite core power line choke from the TDK EPCOS B82747E6 series. It features an inductance of 570 µH at 100 kHz and supports a maximum DC current of 35 A. The component has a maximum self-resonant frequency of 100 kHz and a typical DC resistance of 1.4 mΩ. Rated for 600 V AC, it operates within a temperature range of -40°C to +125°C. Physical dimensions include a 65 mm diameter and 20 mm lead pitch.
Feature Summary
- Triple-phase current-compensated ring core design for balanced load handling
- High saturation capability supporting up to 35 A continuous current
- Compliant with major international safety standards including UL, VDE, and IEC
Applications
- Three-phase power supply input filtering
- Industrial motor drive EMC suppression
- Battery charger input stages
Procurement Notes
Verify the specific suffix against official TDK datasheets to confirm electrical ratings and pinout compatibility. Ensure the procurement channel provides original manufacturer documentation to validate RoHS compliance and safety certifications such as UL or VDE before integration into certified equipment designs.
Selection Notes
Select this component when high current handling and low impedance are required for three-phase systems. The 570 µH value targets specific noise frequencies at 100 kHz testing conditions. Verify that the physical footprint fits the PCB layout constraints regarding the 20 mm lead pitch and 65 mm body diameter.
Part Context
This part belongs to the B82747E6 series of current-compensated ring core triple chokes manufactured by TDK Electronics following its acquisition of EPCOS components business. These components are engineered for robust performance in industrial environments requiring reliable electromagnetic interference suppression in three-phase circuits.
Replacement Considerations
Consult official TDK cross-reference lists for verified substitutes. Generic equivalents may not match the specific 570 µH tolerance or 35 A thermal limits.
