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 [...]

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, [...]

Civilian DC high voltage ceramic capacitors are mainly used in mechanical equipment testing instruments. Such as X-RAY, CT machine, DC high-voltage generator, mainly for voltage doubling, voltage division, coupling, carrier and other functions. The selection of DC high voltage ceramic capacitors is different due to different usage occasions. Generally, low-frequency dielectric ceramic capacitors such as Y5V [...]

AC high voltage ceramic capacitor are mainly used in AC voltage work situations, such as power testing equipment, national grid equipment, etc. AC high-voltage ceramic capacitors have high requirements for various indicators of the capacitor, and generally require the following parameters: 1. AC working voltage; 2. Lightning impulse voltage; 3. Partial discharge level; 4. Temperature change [...]
