Current Transformer

Product Description:

Ensure Reliable Power Management with our precision current transformers (CTs), designed to deliver high-accuracy current sensing, voltage conversion, and impedance matching in compact, energy-efficient packages. Ideal for consumer electronics and industrial power systems, these CTs provide critical isolation and signal conditioning while meeting stringent safety and performance demands.

Features & Benefits:
✅ Multi-Functional Performance – Enables voltage transformation, current scaling, and impedance conversion with <±1% linearity error for stable power delivery.
✅ Ultra-Compact Design – Space-saving SMD and through-hole packages (6mm to 20mm) optimized for PCB integration in smartphone chargers, laptop adapters, and server PSUs.
✅ Enhanced Safety Isolation – Withstands up to 4.3kV AC isolation voltage, complying with UL 60950-1 and IEC 62368-1 safety standards.
✅ Low Power Loss – Core losses reduced by 25% compared to conventional CTs, critical for energy-efficient devices like LED displays and projectors.
✅ Wide Frequency Range – Operates at 50Hz to 1MHz, supporting both line-frequency and high-speed switching applications.
