Monolithic capacitor

Introduction to product description: Since the overall capacitor is not a conductor, it reflects the phenomenon of electrification at both ends through regular AC turns. Therefore, in the circuit, it can be connected in parallel with other components to allow the AC to pass through, and the DC to be blocked. The role of bypass. In an AC circuit, the overall capacitor is charged and discharged according to the polarity change of the input signal, so that the circuit connecting the two ends of the overall capacitor is in a conductive state, which plays a role of coupling. Generally speaking, the monolithic capacitor connected to the input of the amplifier or operational amplifier is a coupling integral capacitor; the monolithic capacitor connected to the emitter of the amplifier or operational amplifier is a bypass integral capacitor, and these two types of capacitors are mainly type II integral Capacitors, especially 0.1uf capacitors.

Product Details

product description:

Monolithic capacitors, also known as MLCCs, are widely used in electronic precision instruments. Various small electronic devices are used for resonance, coupling, filtering, and bypass.

Features:

Good temperature and frequency characteristics. Generally speaking, the capacitance decreases as the frequency increases. The overall capacitance decreases slightly, and the capacity is relatively stable.

Product Features:

1. Energy storage exchange

This is the most basic function of monolithic capacitors, mainly to generate and discharge a kind of electrical energy through its charge and discharge process. In some cases, it can even replace small aluminum electrolytic capacitors and tantalum electrolytic capacitors.

2. Since the overall capacitor is not a conductive body, it reflects the phenomenon of electrification at both ends through regular AC turns. Therefore, in the circuit, it can be connected in parallel with other components to allow AC to pass, while DC is blocked, acting as a bypass The role of.

In an AC circuit, the overall capacitor is charged and discharged according to the polarity change of the input signal, so that the circuit connecting the two ends of the overall capacitor is in a conductive state, which plays a role of coupling. Generally speaking, the monolithic capacitor connected to the input of the amplifier or operational amplifier is a coupling integral capacitor; the monolithic capacitor connected to the emitter of the amplifier or operational amplifier is a bypass integral capacitor, and these two types of capacitors are mainly type II integral Capacitors, especially 0.1uf capacitors.

Three, frequency discrimination filtering

In an AC circuit, a single-stone capacitor can be used to separate a multi-frequency mixed signal. Generally speaking, we can use a reasonable overall capacitor capacitance to filter out most of the low-frequency signals. This is mainly high frequency or ultra high frequency overall capacitance.

Fourth, surge voltage suppression

Since the monolithic capacitor is an energy storage element, it can not only remove short-term surge pulse signals in the circuit, but also absorb the remaining energy generated by voltage fluctuations in the circuit. Filtering is mainly high-frequency products.
