What are the advantages of Yageo ceramic chip capacitor ? YAGEO chip capacitor (MLCC) is a capacitor material. The full name of chip capacitor is: multi-layer (laminated, laminated) chip ceramic capacitor, also known as chip capacitor, chip capacitor. Ceramic chip capacitors have a greater advantage than other capacitors. Due to their small size and powerful effects, they are often used in precision electronic products. Let’s take a look at the advantages of YAGEO ceramic chip capacitors.

MLCC. Different dielectric specifications are commonly used such as C0G (NP0), X7R, Z5U, Y5V, etc. Different specifications have different characteristics and uses. . The main difference between C0G, X7R, Z5U and Y5V is their different filling media. Under the same volume, capacitors composed of different filling media have different capacities, and the resulting dielectric loss and capacity stability of the capacitor are also different. Therefore, when using capacitors, the capacitor should be used according to the different functions of the capacitor in the circuit. Use different capacitors.
Yageo chip ceramic capacitors are currently used in relatively large quantities of electronic components. Take the chip capacitors produced by YAGEO as an example. They are available in different materials such as NPO, X7R, X5R, Y5V, etc. Capacitors made of different materials have different the use of. The following introduces the performance and applications of NPO, X7R, Z5U and Y5V capacitors. The main difference between
NPO, X7R, Z5U and Y5V is their different filling media. Under the same volume, Yageo capacitors composed of different filling media have different capacities, which will lead to different dielectric losses and capacity stability of the capacitors. Therefore, when using capacitors, different capacitors should be selected according to their different functions in the circuit.
1. Yageo NPO capacitor
NPO is the most commonly used Yageo chip ceramic capacitor with temperature compensation characteristics. Its filling medium is composed of rubidium, samarium and some other rare oxides.
Yageo NPO capacitors are one of the Yageo capacitors with the most stable capacitance and dielectric loss. When the temperature is from -55℃ to +125℃, the capacitance change is 0±30ppm/℃, and the change in capacitance with frequency is less than ±0.3ΔC. The drift or hysteresis of NPO capacitors is less than ±0.05%, which is negligible compared with film capacitors greater than ±2%. Its typical change in capacity relative to service life is less than ±0.1%. NPO capacitors have different capacitance and dielectric loss characteristics with frequency depending on the packaging form. Large package sizes have better frequency characteristics than small package sizes.
NPO capacitors are suitable for tank capacitors in oscillators and resonators, as well as Yageo coupling capacitors in high-frequency circuits.
2. Yageo X7R capacitor
Yageo X7R capacitor is called a temperature-stable ceramic capacitor. When the temperature is from -55°C to +125°C, the capacitance change is 15%. It should be noted that the capacitor capacity change is non-linear at this time.
The capacity of the Yageo X7R capacitor is different under different voltage and frequency conditions. It also changes with time, approximately 1%ΔC every 10 years, which means a change of about 5% in 10 years.
Yageo X7R capacitors are mainly used in industrial applications with low requirements, and under the condition that the change in capacity when the voltage changes is acceptable. Its main feature is that the capacitance can be larger under the same volume.
3. Yageo X5R capacitor
Yageo X5R capacitor is called a temperature-stable ceramic capacitor. When the temperature is from -55°C to +85°C, the capacitance change is 15%. It should be noted that the capacitor capacity change is non-linear at this time.
Yageo X5R capacitors are mainly used in bypass, coupling or other circuits that do not require high loss and capacitance stability. Its main feature is that the capacitance can be larger under the same volume. Yageo X5R chip capacitor capacity can reach up to 47μF.
4. Yageo Y5V capacitor
Yageo Y5V capacitor is a general capacitor with a certain temperature limit. Its capacity can change from +22% to -82% in the range of -30℃ to 85℃.
The high dielectric constant of Yageo Y5V allows the fabrication of capacitors up to 22μF in smaller physical sizes. (Yageo Y5V capacitor as an example)
The value range of Yageo Y5V capacitor is as shown in the following table:
Operating temperature range -30℃ — +85℃
Temperature characteristics +22% —- -82%
Maximum dielectric loss 5%

This is about the advantages of YAGEO ceramic chip capacitors. The selection of YAGEO chip capacitors is very important. Many companies need engineers when they need products. Due to negligence, I did not understand the specific performance parameters of YAGEO chip capacitors and could not use them after purchase. To avoid such embarrassing things, it is best to choose the model of chip capacitors after understanding the parameters of YAGEO chip capacitors.
