What are the different types of dielectric materials for chip capacitors?

The X5R, X7R, Y5V, Z5U, COG, COH and other parameters of the chip capacitor describe the type of dielectric material used by the capacitor, temperature characteristics and error parameters, different values also correspond to a certain range of capacitance capacity, what are the differences?

What are the applications of chip capacitors in the electrical field?

As a passive component, the chip capacitor is often used in the power supply circuit to achieve bypass, decoupling, filtering and energy storage, etc., and the main role in the signal circuit is coupling, oscillation/synchronization and time constant. Let's add one explanation to each of these.

Patch capacitor you need to know these six points

The chip capacitor is a kind of capacitor material. Chip capacitor full name: multi-layer (laminated, laminated) chip ceramic capacitor, also known as chip capacitor, chip capacity. There are two ways to express the chip capacitance, one is expressed in inch units, and the other is expressed in millimeter units.

Naming rules and parameter explanation of chip capacitors

The name of the chip capacitor, domestic and foreign manufacturers have this difference, but the parameters contained are the same. The name of the chip capacitor contains the parameters: 1, the size of the chip capacitor: (0201, 0402, 0603, 0805, 1206, 1210, 1808, 1812, 2220, 2225)

The function and characteristics of the chip capacitor

(1) Decoupling: The capacitor is called the "decoupling" capacitor in the decoupling circuit, and its role is the natural decoupling effect, mainly to remove the coupling noise and the noise of the output signal that cannot be seen in the amplifier.

How to look at the size of the chip capacitor? Inch units and millimeter units

There are two kinds of size representation of the chip capacitor, one is expressed in inches, and the other is expressed in millimeters. The series models of the chip capacitor are 0402, 0603, 0805, 1206, 1210, 1808, 1812, 2010, 2225, 2512, which is inch representation. 04 indicates that the length is 0.04 inches, 02 indicates that the width is 0.02 inches, and other similar model sizes (mm).

Common resistor classification and derating usage rules

Resistance can be divided into three categories: fixed linear resistance, fixed nonlinear resistance, variable resistance, the reliability of the resistance mainly depends on the temperature of the resistance, and the temperature is the effect of the superposition of the ambient temperature and the heat generated by its own power loss.

Characteristics and uses of alloy resistance

Alloy resistance using alloy as the current medium resistance, alloy resistance is often called: metal alloy resistance, copper alloy resistance, sampling resistance, current detection resistance, low resistance value resistance, sensing resistance and so on.
