Monolithic capacitors are another name for multilayer ceramic capacitors. The English name monolithic ceramic capacitor or multi-layer ceramic capacitor, referred to as MLCC, is widely used in electronic precision instruments. Various small electronic devices are used for resonance, coupling, filtering, and bypass. Monolithic capacitors are larger than ordinary ceramic capacitors (10pF~10μF), and have the advantages of large capacitance, small size, high reliability, stable capacitance, high temperature resistance, good insulation, and low cost, so they are widely used. Monolithic capacitors can not only replace mica capacitors and paper capacitors, but also replace certain tantalum capacitors, and are widely used in small and ultra-small electronic devices (such as liquid crystal watches and micro instruments).With the improvement of the reliability and integration of chip-capacity products, the scope of their use becomes wider and wider, and they are widely used in various civilian electronic complete machines and electronic equipment. Such as computers, telephones, program-controlled switches, sophisticated testing instruments, radar communications, etc.
Structure:
The basic structure of a simple parallel plate capacitor is an insulating intermediate dielectric layer plus two conductive metal electrodes. The basic structure is as follows:
Therefore, the structure of multilayer chip ceramic capacitors mainly includes three parts: ceramic dielectric, metal inner electrode, and metal outer electrode. The multilayer chip ceramic capacitor is a multi-layer laminated structure, in short, it is a parallel body of multiple simple parallel plate capacitors.
• Good temperature characteristics
• Good frequency characteristics
• Generally, as the frequency rises, the capacitance of the capacitor shows a decreasing law, while the monolithic capacitor decreases less and the capacity is relatively stable.
• Pass through
• Small volume
• Bigger than capacity
• Long life High reliability
• Suitable for surface mounting
1. Energy storage exchange
This is the most basic function of the monolithic capacitor, which is mainly used to generate and release an electric energy through its charging and discharging process. This is mainly based on large-capacity type II monolithic capacitors, and in some cases can even replace small aluminum electrolytic capacitors and tantalum electrolytic capacitors.
2. Separate direct communication (bypass and coupling)
Since the monolithic capacitor is not a conducting body, it reflects the phenomenon of electrification at both ends through the regular rotation of the AC. Therefore, it can be connected in parallel with other components in the circuit to allow the AC to pass through and the DC to be blocked. , Plays the role of bypass. In an AC circuit, the monolithic capacitor is charged and discharged following the change in the polarity of the input signal, so that the circuit connecting the two ends of the monolithic capacitor is in a conductive state and acts as a coupling. Generally speaking, the monolithic capacitor connected to the input of the amplifier or operational amplifier is a coupling monolithic capacitor; the monolithic capacitor connected to the emitter of the amplifier or operational amplifier is a bypass monolithic capacitor. Both are mainly type II monolithic capacitors, especially 0.1uF capacitors.
3. Frequency discrimination
filtering In an AC circuit, for a multi-frequency mixed signal, we can use a monolithic capacitor to separate its parts. Generally speaking, we can use a monolithic capacitor with a reasonable capacitance to filter out most of the low-frequency signals. This is mainly based on high-frequency or ultra-high frequency monolithic capacitors.
4. Suppression of surge voltage
Because the monolithic capacitor is an energy storage element, in the circuit, it can remove those short-term surge pulse signals, and can also absorb the excess energy generated by the voltage fluctuations in the circuit. The filtering is mainly based on high-frequency products.
