Capacitor technical knowledge, principles and fundamentals
Regarding the SMD high voltage capacitors, he actually has another name, called ceramic multilayer chip capacitors, which can be regarded as a production process using ceramic powder. Its interior is [...]
Is the larger the capacitance the better? Intuitively, it seems that the larger the energy storage capacitor, the stronger the current compensation capability provided by the IC. Therefore, many people [...]
How to simply judge the quality of motherboard capacitors from the appearance? You can start with the following aspects: Distinguish by color: black capacitors are the worst, green capacitors are [...]
Farad capacitors are also super capacitors. The capacity of supercapacitors is much larger than that of ordinary capacitors. Because of its large capacity and the same external performance as a [...]
The Uses of ceramic capacitors, this type of capacitors are commonly used in high-frequency circuits and high-voltage circuits, temperature compensation, and high temperature stability circuits. Bypass (decoupling) This is to [...]
Important indicators about capacitance Capacity: The capacity of the capacitor, that is, the capacity of the stored charge. The basic unit of capacity is farad (F), but on the motherboard [...]
General capacitor failure phenomena: capacitor open circuit, breakdown, leakage, breakdown after power-on cause of issue 1. Open circuit of components After the capacitor can be developed open circuit, there is [...]
The power amplifier power supply filter capacitor has three functions: 1. Filter the pulsed DC power obtained after rectification to reduce AC interference. 2. High-speed power supply. 3. Provide access [...]
Common problems in the selection of film capacitors A. improper selection of rated voltage The rated voltage is improperly selected, and the most frequent place is the resonant circuit part [...]
Discrimination of Electrolytic Capacitor Polarity The capacitance is deviated. Generally, the polarity will be marked with a symbol on the capacitor. Generally, the negative electrode is marked as "-" and [...]
