Micro Voltage Transformer operate on the principle of electromagnetic induction, where a primary voltage applied to the micro-windings generates a magnetic field in a nano-crystalline core, inducing a precisely scaled secondary voltage. These devices achieve miniaturization through advanced core materials and optimized winding techniques, maintaining accuracy while reducing size.
Product Features
1. Compact and Lightweight: With volumes under 2 cm³ and weights of 3–5 grams, MVTs integrate into high-density circuits, portable devices, and wearables without compromising performance.
