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 [...]

Our company summarizes the following customers often encountered A few points: 1 Voltage and capacity of Snap-in aluminum electrolytics capacitor; Undoubtedly, the voltage [...]

High frequency capacitors are basically composed of passive components, active devices and passive networks. The frequency characteristics of components used in high-frequency circuits are different from those used in low-frequency circuits. Passive linear components in high frequency circuits are mainly resistors (devices), capacitors (devices) and inductors (devices). Features of high frequency capacitors: 1. High-Q C0G series [...]

In electronic circuits, decoupling capacitor and bypass capacitors both play an anti-interference role. The location of the capacitor is different, and the name is different. For the same circuit, the bypass capacitor takes the high-frequency noise in the input signal as the filtering object to filter out the high-frequency clutter carried by the previous stage, and [...]
