Capacitor technical knowledge, principles and fundamentals
Can capacitors of the same patch size be replaced? Capacitors of the same package cannot be distinguished from the appearance. The capacitors of 100nF and 1nF in the same package are difficult to distinguish from the appearance, although they may be different in thickness. 1. If the chip on the power side of the chip may [...]
Safety capacitors are safety capacitors that will not affect the human body even if they fail. They are favored because of their high safety expertise. However, for the purchase or use of safety capacitors, routine testing of safety capacitors is an indispensable process. 1. Rotate the shaft gently with your hands. It should feel very smooth, [...]
CBB capacitors and safety capacitors have certain similarities in their functions. For example, they can be used for filtering, but there are many differences between them. What is the difference between CBB capacitors and safety capacitors? What are the main types of safety capacitors? Although there are many types of safety capacitors, the most frequently used [...]
ceramic capacitors is a capacitor that uses ceramic materials as a medium, coats a layer of metal film on the ceramic surface, and then sinters at a high temperature as an electrode. It is usually used in high-stability oscillating loops as loops, bypass capacitors and pad capacitors. As long as the ceramic capacitor is aimed at [...]
The meaning of parasitic is that there is no capacitance designed in that place, but because there is always mutual capacitance between wiring, mutual capacitance is like parasitic between wiring, so it is called parasitic capacitance, also called stray capacitance. 1. On the other hand, in addition to the capacitance between the plates of the sensor, [...]
