Color code inductor
A color code inductor is an inductor with a fixed inductance, and its inductance sign method is marked with a color ring like a resistor.
The coil that restricts the passage of alternating current is called a choke, and is divided into a high frequency choke coil and a low frequency choke coil.
The deflection yoke is the load of the output stage of the television scanning circuit. The deflection yoke requires: high deflection sensitivity, uniform magnetic field, high Q value, small size and low price.
The most basic component of a knitted fabric is a spatial curve. It consists of two ring columns, a needle arc and a sinker arc (or extension line).
