en.Wedoany.com Reported - TDK Corporation has recently expanded its passive component product line with the introduction of the B82722V6*B040 series of high-voltage common mode chokes. This series is specifically designed for next-generation power conversion systems, supporting DC link voltages up to 1250V or AC voltages up to 630V, to meet the demands of modern high-voltage architectures for electromagnetic interference suppression, insulation coordination, and PCB space optimization.
The choke measures 23×15.5×24 mm, making it suitable for space-constrained application scenarios while maintaining high performance. The product's inductance values range from 3.3 mH to 22 mH, with rated currents from 0.85 A to 3.0 A at 70°C, allowing designers flexible selection based on specific filtering and current handling requirements.
This series employs a multilayer solid insulation structure, with isolation performance verified through 3750V line-to-line testing, and utilizes automated winding processes to enhance consistency and reliability. This contributes to achieving high resonant frequencies and low stray inductance of approximately 0.6%, effectively suppressing common-mode and symmetrical interference.
The choke's ferrite core is coated with epoxy resin, and the plastic housing complies with the UL 94 V-0 flame retardant standard, ensuring safety and compliance. The series design adheres to IEC 60938-2 and IEC/UL 60939-3 standards, is compatible with wave soldering processes and vertical mounting configurations, facilitating integration into existing PCB layouts.
The B82722V6*B040 series is suitable for applications such as power converters, industrial motor drives, and switched-mode power supplies. These systems often utilize wide-bandgap semiconductors like SiC and GaN devices, operating at higher switching frequencies and voltages, requiring compact designs and efficient EMI filtering.
This series enables compact high-voltage DC link designs while maintaining effective EMI suppression. It complies with RoHS standards, supporting environmentally regulated application scenarios.
