Understand the in-line ceramic capacitor

According to the dielectric capacitor dielectric, there are two types of dielectric (NP0, C0G), two types of dielectric (X7R, 2X1) and three types of dielectric (Y5V, 2F4) ceramic capacitors. EIA RS-198MLCC (Class 1) - miniaturization, high frequency, ultra low loss, low ESR, high stability, high withstand voltage, high insulation, high reliability, no polarity, low capacitance, low cost, high temperature resistance. Mainly used in high frequency circuits.

MLCC (Class 2) - miniaturization, high specific volume, medium and high voltage, non-polarity, high reliability, high temperature resistance, low ESR, low cost. Mainly used in medium and low frequency circuits for isolation, coupling, bypass and filtering, etc. Capacitor use.

Identification method of in-line ceramic capacitor: The identification method of the capacitance is basically the same as the identification method of the resistance, and there are three types: the direct label method, the color scale method and the number standard method. The basic unit of the capacitance is pulled (F), and other units are: millifarad (mF), microfarad (μF)/mju:/, nanofarad (nF), and picofarad (pF). Where: 1 Farad = 1000 millifarads (mF), 1 millifarad = 1000 microfarads (μF), 1 microfarad = 1000 nanofarads (nF), 1 nanofarad = 1000 picofarads (pF)

The capacity of a large-capacity ceramic capacitor is directly indicated on the capacitor. For example, 10 μF/16V, the capacity of a small-capacity ceramic capacitor is represented by letters or numbers on the capacitor. Letter notation: 1F=1000 μF 1P2= 1.2PF 1nF=1000PF. Digital notation: The three-digit representation is also called the digital representation of the capacitance. The first two digits of the three digits are the significant digits of the nominal capacity, and the third digit represents the number of zeros following the significant digit, all of which are in pF.
