one. Chip capacitor definition: chip ceramic capacitors, also known as chip capacitors. .
two. SMD capacitor classification: It can be divided into two types: non-polar and polar. The following two types of non-polar capacitors are common, namely 0805 and 0603; polar capacitors are tantalum capacitors. SMD components are close to the circuit board. Therefore, the temperature stability is required to be high, so the chip capacitors are mostly tantalum capacitors.

two. SMD capacitor classification: It can be divided into two types: non-polar and polar. The following two types of non-polar capacitors are common, namely 0805 and 0603; polar capacitors are tantalum capacitors. SMD components are close to the circuit board. Therefore, the temperature stability is required to be high, so the chip capacitors are mostly tantalum capacitors. SMD capacitors are commonly found in the following categories:

1. NPO capacitor NPO is a commonly used monolithic ceramic capacitor with temperature compensation characteristics. Its filling medium is composed of rubidium, samarium and some other rare oxides. NPO capacitors are one of the capacitors with stable capacitance and dielectric loss. When the temperature is from -55℃ to 125℃, the capacitance change is 0±30ppm/℃, and the capacitance change with frequency is less than ±0.3ΔC. The drift or hysteresis of NPO capacitors is less than ±0.05%, which is negligible compared to film capacitors greater than ±2%. Its typical capacity versus lifetime variation is less than ±0.1%. NPO capacitors have different characteristics of capacitance and dielectric loss with frequency depending on the package form. Larger package size has better frequency characteristics than small package size.

2. X7R capacitors X7R capacitors are called temperature-stable ceramic capacitors. When the temperature is from -55°C to 125°C, the capacitance change is 15%. It should be noted that the capacitance change of the capacitor is non-linear at this time. The capacity of the X7R capacitor is different under different voltage and frequency conditions, and it also changes with time, about 1% ΔC every 10 years, which shows about a 5% change in 10 years. X7R capacitors are mainly used in less demanding industrial applications where the change in capacitance when the voltage changes is acceptable. Its main feature is that the capacitance can be relatively large under the same volume.

3. Z5U capacitors Z5U capacitors are called "universal" ceramic monolithic capacitors. The first thing to consider here is the operating temperature range, the main thing for the Z5U capacitor is its small size and low cost. For the above three ceramic monolithic capacitors, the Z5U capacitor has the same capacitance under the same volume. However, its capacitance is greatly affected by the environment and working conditions, and its aging rate can decrease by 5% every 10 years. Despite its unstable capacity, it has a wide range of applications due to its small size, low equivalent series inductance (ESL) and equivalent series resistance (ESR), and good frequency response.

4. Y5V Capacitor Y5V capacitor is a general-purpose capacitor with a certain temperature limit, and its capacitance can vary from 22% to -82% in the range of -30°C to 85°C. The high dielectric constant of Y5V allows fabrication of capacitors up to 4.7µF in small physical size
