Monolithic capacitor small space as a large

Monolithic capacitors are another name for multilayer ceramic capacitors, referred to as MLCC, which are widely used in various small electronic devices for resonance, coupling, filtering, and bypass. Features: good temperature characteristics and good frequency characteristics. Generally, as the frequency increases, the capacitance decreases, and the monolithic capacitance decreases less and the capacity is relatively stable.

Although the monolithic capacitor is small in size, large in specific volume, long in life, high in reliability, suitable for surface mounting and the like. The role is as follows:

1. Energy storage exchange: This is the basic function of monolithic capacitors, mainly through the charging and discharging process to generate and apply an electric energy.

2, through the straight through: because the monolithic capacitor is not a conducting body, it is through the regular steering of the alternating current to show the phenomenon of charging at both ends, therefore, in the circuit it can be connected in parallel with other components, so that the communication through The DC is blocked and acts as a bypass.

3. Frequency discrimination filter: In the AC circuit, for a multi-frequency mixed signal, we can separate it with a monolithic capacitor. In general, we can use a monolithic capacitor with a reasonable capacitance to make most of the low frequency. The signal is filtered out.

4. Suppression of Surge Voltage: Since the monolithic capacitor is an energy storage component, it can remove those transient surge signals in the circuit, and can also absorb the excess amount generated by the voltage fluctuations in the circuit.

Every capacitor has its role, we need to understand clearly, in order to use it better! If you need a sample test, please contact us for free.
