Features Designed to transform voltage or change the impedance of a load. The primary and secondary windings are closely coupled. Sufficient passband, the original winding inductance is large, the leakage inductance is small, the influence of hysteresis loss can be reduced. Stable performance, high reliability, convenient to use. Used as components for circuits such as voltage amplification and power output in radio communication, broadcast television, and automatic control.
