|1. Winding type
It is characterized by a wide range of inductance (mH ~ H), high precision of inductance, low loss (ie Q large), allow the current is large, the production process inheritance is strong, simple, low cost, but the disadvantage is further Miniaturization is limited.
2. Lamination type
This type of chip power inductor has good magnetic shielding, high sintering density and good mechanical strength. There are also some disadvantages, such as the low pass rate, high cost, small inductance and low Q value. Compared with the wound chip inductor, the lamination tyoe chip power inductor is much smaller in size, more conducive to the miniaturization of the circuit, and more suitable for automated surface installation and production.
3. Thin film type
The characteristics of film type chip power inductor are high Q value, high accuracy, high stability and small volume in the microwave frequency band. Its internal electrodes concentrated in the same level to make sure the little change in parameters. The frequency characteristics are also quite good above 100MHz.
4. Weaving type
This kind of chip power inductor is characterized by a larger unit volume inductance at 1MHz than other chip inductors, smaller size, easier installation on the substrate. Often used as a micro-magnetic element for power processing.
