Main uses of wound patch inductor: This product is widely used in xDSL modules and modulation modulators, computers, digital cameras and other mini TVs, LCD TVs, cameras, portable VRC, car audio, thin radios, TV modulators, cordless phones, etc.
Matters needing attention in winding process:
Choose the winding method according to the needs of the circuit;
When the winding is hollow, the winding method is determined according to the requirements of the circuit, the size of the inductance and the diameter of the coil frame. Interwound coils are suitable for high-frequency and ultra-high-frequency circuits. When the number of turns is less than 3-5 turns, it can have better characteristics without skeleton;
The q value is high, which can reach 150-400, and the stability is high;
Single-layer closely wound coil is suitable for short-wave and medium-wave circuits, with q value up to 150-250 and high stability;
The basic functions of winding patch inductor are filtering, oscillation, delay, trap, etc.
Image statement: pass DC and block AC;
In electronic circuits, it can form high-pass or low-pass filters, phase-shift circuits and resonant circuits with resistors or capacitors. Transformers can be AC coupled, transformed, converted and impedance converted.
The function of wound patch inductance seems to be somewhat eversed. We say that capacitors go straight through cross resistance, while inductors are just the opposite. Its function is through direct resistance. Originally, the direction of the magnetic field generated when DC passes through the inductor is consistent and will not change.
