Overview
The B82747E6203A040 is a current-compensated ring core triple choke manufactured by EPCOS - TDK Electronics. It features a vertical package with six PC pins for through-hole mounting. The component provides a nominal inductance of 1.5 mH at 10 kHz and supports a current rating of 20 A. Its typical DC resistance is 4.2 mOhm. This power line choke is designed for three-line applications, ensuring compliance with RoHS standards.
Feature Summary
- Utilizes a current-compensated ring core design for effective noise suppression
- Configured as a triple choke for three-line power filtering
- Supports high current handling capabilities suitable for robust power applications
Applications
- Power line filtering in industrial electronics
- EMI suppression in three-phase power systems
- Noise reduction in power supply inputs
Procurement Notes
Verify the specific ordering code B82747E6203A040 against official TDK documentation to confirm pin configuration and electrical ratings. Ensure compatibility with existing PCB layouts requiring vertical through-hole mounting. Cross-reference datasheet specifications for thermal performance under rated load conditions before integration.
Selection Notes
Select this component when three-line common mode chokes are required for high-current power applications. The 1.5 mH inductance value targets specific frequency ranges for EMI mitigation. Verify that the 20 A current rating aligns with system requirements and that the vertical package fits the mechanical constraints of the enclosure.
Part Context
This part belongs to the B82747 series of power line chokes from EPCOS, now integrated into TDK Electronics. The series focuses on providing reliable electromagnetic interference suppression for power lines. The B82747E variant specifically denotes the ring core construction and terminal style, distinguishing it from other housing types within the broader product family.
Replacement Considerations
Check for direct substitutes such as B82747E6253A040 or B82747E6353A040 if different inductance values are acceptable. Ensure any replacement maintains the same current rating and physical footprint to avoid redesigning the mounting structure.
