INF
The SQ series common mode choke is designed for EMI suppression in AC power lines and switching power supplies. It utilizes a high-permeability MnZn ferrite square core and optimized winding structure to provide excellent common-mode noise attenuation over a wide frequency range.
With low DC resistance, high current capability, and stable thermal performance, the SQ series is widely used in SMPS, LED drivers, industrial power supplies, and EMI filters to improve electromagnetic compatibility and system reliability.
Material Quality:
We use premium raw materials and maintain long-term partnerships with leading suppliers in China to ensure stable supply and high product quality. Strict procurement inspections guarantee that each batch of lead inductors and current transformers meets the highest standards.
Production Process:
Our experienced team is skilled in various manufacturing techniques, ensuring smooth production of high-frequency transformers.
We adhere to ISO9001 and other international quality standards, holding multiple certifications to guarantee reliability and performance.
Fast Delivery:
With a robust supply chain and efficient production management, we respond quickly to demands, reducing lead times for current transformers and high-frequency transformers.
