Five precautions for replacing capacitors Fixed capacitors are prone to failure phenomena such as leakage, short circuit, open circuit, poor contact of the internal leads of the capacitor (the pole piece and the lead connection), etc. Especially electrolytic capacitors have a much higher failure rate than other types of capacitors. The frequent failure phenomena of electrolytic [...]
What is a good capacitor 1.The larger the capacitance, the better. Many people tend to use large-capacity capacitors in the replacement of capacitors. We know that although the larger the capacitance, the stronger the current compensation capability provided by the IC. Not to mention the increase in capacitance brought about by the increase in volume, which [...]
Monolithic ceramic capacitors (commonly known as chip capacitor) are commonly used components that are currently used in relatively large quantities. For the chip capacitor produced by xuansn, there are different specifications such as NPO, X7R, Z5U, and Y5V, and different specifications have different uses. Below we only introduce the performance and application of the commonly used [...]
1. Capacitance are generally represented by "C" plus a number in the circuit (for example, C13 represents the capacitor numbered 13). A capacitor is a component composed of two metal films close together and separated by an insulating material. The characteristic of the capacitor is mainly to block DC and pass AC. The size of the capacitor [...]
The main technical indicators of capacitors are capacitance, withstand voltage and temperature. In addition to these three main indicators, the more important of other indicators is equivalent series resistance (ESR). Some capacitors have a golden strip line with a big hollow letter "I" printed on it, which indicates that the capacitor is a LOW ESR low-loss [...]
