4． Structure
Capacitor consistsof enclosure and core. Enclosure is made of full automatic welding stainlesssteel plates, and is welded high-strength hydraulic type bushings on the upper cover. The capacitor is filled with high-isolation electrical liquid medium of C101 type from France inside.
Core is made up bycomponents and insulation. The solid medium of components selects doublecoarsening polypropylene film from Finland, polar plate uses ultrathin aluminumfoil, the structure of folding and protuberant foil improves partial dischargelevel.
Some high-capacity products can be equipped with internal fuses; the new structure of internalfuses makes the products more reliable.
The products with internal discharge resistor adopts high quality HV glass glaze resistor to decrease the residual voltage of capacitor from√2Un to below 50V within 5min after switch off.

- Q: Is the capacitor attached to the carbon foil positive?
- The negative electrode of the capacitor is made of electrolyte, the electrolyte is generally composed of boric acid, ammonia, ethylene glycol and other components.
- Q: What is the phase-shifting capacitor, what is the difference between it and the general capacitor
- Assuming a capacitor has upper and lower poles, the upper plate is connected with the positive pole, the lower plate is connected with the negative electrode, connected with the power source, the potential difference between the two plates is formed, and the potential difference between the two electrodes is equal,
- Q: What is the relationship between capacitance and voltage?
- In your case, you can think of two capacitors as two containers, 5v capacity than 10v half (because they are 0.01uF),
- Q: Capacitance can pass high frequency resistance low frequency principle
- When the negative half of the alternating current arrives, it will generate the current, first offset the original charge on the capacitor that the opposite charge, continue to charge to full.
- Q: Does the size of the capacitor affect the power consumption?
- Therefore, users not only need to understand the performance of various types of capacitors and general characteristics, but also must understand the advantages and disadvantages of various components under given use, mechanical or environmental constraints, etc. This article describes the main parameters of the capacitor and application , For readers to choose the type of capacitor used.
- Q: What is the principle of capacitance isolation?
- When the capacitor is connected to the DC circuit, there will be a brief charging process. When the positive and negative plates are filled with charge (when the voltage across the capacitor is equal to the supply voltage), there is no current and then flow, so the capacitor is isolated DC current
- Q: Does anyone know the difference between the stray inductance of the capacitor and the parasitic inductance?
- This impedance can not be ignored in the presence of high frequency current, with particular note that the bypass capacitor needs to pass through the two vias when connecting the power plane and the formation so that the parasitic inductance of the vias is multiplied.
- Q: On the ground resistance, what role the capacitor
- The capacitor used in the bypass circuit is called the bypass capacitor. If the signal is removed from the signal in the circuit, the bypass capacitor circuit can be used. According to the frequency of the removed signal, there is a full frequency domain (all AC signals ) Bypass capacitor circuit and high frequency bypass capacitor circuit.
- Q: How to identify high voltage capacitors is good or bad
- You have no voltage regulator, if there is, with a voltage regulator, an ammeter a voltmeter (available multimeter instead) to the capacitor plus an integer current (controlled by a voltage regulator), and then calculate the capacitance based on the voltage reading and current reading Impedance, and then divided by 3184 calculated by the tolerance value, the results and the capacitor nameplate on the standard almost no capacitance, and the other side of the capacitor is broken
- Q: Capacitance for AC and DC effects?
- In the sine wave AC circuit, the current size of the current flowing through the capacitor can be quantitatively calculated. Specifically, the voltage U is in volts (V), the current I is in the unit (A), the capacitance C is expressed by the law (F) (Ω), the frequency of the AC power supply is expressed in Hertz (Hz) units, and the frequency of the AC power supply is expressed in Hits (Hz)
