Sirui-Tech offers high-performance common mode chokes engineered to suppress electromagnetic interference (EMI) in photovoltaic inverters, energy storage systems and EV charging infrastructure.
Our chokes use nanocrystalline or Mn-Zn ferrite cores tailored to specific frequency bands, with impedance curves optimized for differential-mode and common-mode noise in both grid-tied and off-grid renewable systems.
Custom designs are available for various current ratings (1A to 200A), with appropriate creepage and clearance distances to meet safety standards such as IEC 61558 and IEC 62477.
