Monolithic capacitors and ceramic chip capacitor are both ceramic capacitors. They are different in overall structure, appearance, characteristics, capacity, withstand voltage, and application.
Monolithic capacitor are another name for multilayer ceramic capacitor. Monolithic capacitor are composed of a multilayer dielectric and multiple pairs of electrodes, while ceramic capacitor are generally composed of a layer of dielectric and a pair of electrodes. Ceramic capacitors are divided into high frequency There are two types: porcelain and low-frequency porcelain.
Monolithic capacitors are actually made by sintering ceramic chip capacitor after soldering their leads. They are generally square, while ceramic capacitors are chip-shaped, mostly in the shape of a wafer.
3.Capacity and withstand voltage
Under the same volume, the capacitance of the monolithic capacitor is much greater than that of the ceramic capacitor, and the withstand voltage of the ceramic capacitor is higher than that of the monolithic capacitor.
The characteristics of monolithic capacitors are:
- Large and stable electric capacity, the capacity range is 10pF~10uF;
- Small size, smaller than CBB capacitor;
- Good high temperature and humidity resistance;
- Small temperature drift coefficient
The characteristics of ceramic capacitors are:
- Small size and good high frequency characteristics;
- Higher voltage resistance than monolithic capacitors;
- The capacity is small, the maximum is only 0.1uF;
- The price is lower than monolithic capacitors.
Because monolithic capacitors and ceramic chip capacitor have different characteristics, their applications in life are also different. Monolithic capacitors are mainly used in LCD watches, electronic cameras, micro instruments, medical instruments, and electronic tuners; and The application of ceramic capacitors is mainly in the high-frequency oscillation circuit, bypass, and decoupling.
6.The two different capacitors, monolithic capacitor and ceramic capacitor, have similarities, that is, there is no distinction between positive and negative poles. For occasions and equipment requiring large capacity, monolithic capacitors are a reliable choice. If you choose a ceramic capacitor, it will slow down or cause other malfunctions due to insufficient capacity.
