TDK Power Line Ring Core Common Mode Chokes
Proven EMI Suppression Solutions for Power Electronics, Industrial Systems and Next-Generation Energy Designs
TDK is a European market leader in ferrite-based Power Line Chokes, built on decades of expertise in ferrite materials and in-house core production. This unique heritage enables outstanding EMC performance, proven reliability, and a broad portfolio of solutions for demanding power electronics applications.
Together, TDK and Avnet Abacus help engineers identify, evaluate, and implement the right ring core choke technology for their applications, from compact low-voltage designs and power supplies to industrial drives, converters, and high-voltage power architectures.
Why Choose TDK Ring Core Chokes?
TDK's expertise starts at the core. Unlike many suppliers, TDK manufactures its own ferrite cores and combines this capability with highly automated production and extensive EMC know-how.
Superior EMC Performance
Advanced ferrite materials and decades of magnetic design experience deliver excellent common-mode noise suppression and high magnetic efficiency.
Trusted Quality and Reliability
Automated manufacturing processes support high levels of traceability, reproducibility, and product consistency.
Designed for Modern Assembly
Choose from SMT and through-hole technologies, multiple orientations, and mechanically robust designs suitable for automated assembly.
Engineering Support Beyond the Component
TDK's EMC laboratories and simulation capabilities support magnetic, thermal, and mechanical analysis to help engineers achieve faster compliance and design optimisation.
Manufacturing Advantages for Automated Production
TDK continuously develops solutions that help manufacturers improve assembly efficiency and reduce handling complexity.
Global Manufacturing Flexibility
TDK offers multiple manufacturing locations, including specialised "Outside of China” production and sourcing options to support regional and global supply-chain requirements.
