High capacity chip capacitors and ordinary chip capacitors are two common types in electronic components, and they have certain differences in structure, characteristics, and applications. This article will provide a detailed introduction to the differences between high-capacity chip capacitors and ordinary chip capacitors from these aspects.
1、 Structural differences
There is no significant difference in appearance between high capacity chip capacitors and ordinary chip capacitors, both of which are packaged in a chip style and have similar dimensions and shapes. However, there are differences in their internal structure. Ordinary chip capacitors usually adopt a multi-layer structure, composed of multiple layered capacitors, and increase the capacitance value through staggered stacking. High capacitance chip capacitors, on the other hand, adopt a single-layer structure with only one capacitor layer, but their capacitance value is relatively high.
2、 Characteristic differences
Capacitance value: The biggest characteristic of high capacitance chip capacitors is their high capacitance value. Generally speaking, the capacitance range of ordinary chip capacitors is small, usually between tens of picoseconds (pF) and hundreds of microfunctions (uF). The capacitance value of high capacitance chip capacitors can reach several hundred microfaragons or even several milliamperes (mF).
Working voltage: The working voltage range of ordinary chip capacitors is relatively small, usually between tens of volts (V) and hundreds of volts. The working voltage range of high-capacity chip capacitors is relatively large, reaching hundreds or thousands of volts.
Temperature characteristics: The temperature characteristics of ordinary chip capacitors are usually good, and their capacitance values change less when temperature changes. However, the temperature characteristics of high capacitance chip capacitors are relatively poor, and their capacitance values change significantly with the increase or decrease of temperature.
ESR: ESR (Equivalent Series Resistance) is the internal Equivalent series resistance of the capacitor and an important indicator to measure the performance of the capacitor. The ESR of ordinary chip capacitors is generally low and has good conductivity. However, high capacitance chip capacitors have a higher ESR and relatively poor conductivity.
3、 Application differences
Due to the high capacitance value and operating voltage of high capacitance chip capacitors, they are usually used in circuits with high requirements for capacitance values. For example, high capacity chip capacitors are commonly used in high-power circuits such as power filtering, DC/DC converters, and motor drivers to provide stable power supply voltage and current. Ordinary chip capacitors are widely used in various electronic devices, such as mobile phones, computers, televisions and other Consumer electronics.
4、 Summary
In summary, there are significant differences in structure, characteristics, and applications between high capacity chip capacitors and ordinary chip capacitors. High capacitance chip capacitors have high capacitance values and operating voltages, making them suitable for circuits with high capacitance requirements; The common chip capacitor is widely used in various Consumer electronics. Understanding these differences helps us to more accurately select suitable capacitors when designing and selecting electronic circuits.
