Laminated type
It has good magnetic shielding property, high sintering density and good mechanical strength. Shortcomings are low qualified rate, high cost, small inductance, low Q value.
Compared with wound chip inductors, it has many advantages: small size, conducive to the miniaturization of the circuit, closed magnetic circuit, will not interfere with the surrounding components, will not be interfered by adjacent components, conducive to the high-density installation of components; Integrated structure, high reliability; Good heat resistance and weldability; Regular shape, suitable for automatic surface mounting production.
Thin-film type
It has the characteristics of high Q, high precision, high stability and small size in microwave frequency band. The internal electrodes are concentrated in the same layer and the magnetic field distribution is concentrated, which can ensure that the device parameters do not change much after installation, showing good frequency characteristics above 100MHz.
