- 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 electrolytic capacitor inside?
- Electrolytic capacitor is a dielectric of a dielectric electrolyte coating has a polarity, positive and negative can not be connected wrong. Electric capacity (Electric capacity), by the two metal pole, the middle folder with insulating material (medium) composition.
- Q:How does the capacitor work? What does it do?
- The other is the signal filter, that is, the case of alternating current, but also in the AC electrode polarity changes in the process of continuous charge and discharge, in order to AC, if not the capacitance of the two sheds with the amount of change, no matter how the AC can not pass.
- Q:What is the phase-shifting capacitor, what is the difference between it and the general capacitor
- After the power is turned off, the charge will not disappear, nor will it be neutralized (after all, between the two plates is insulated, positive and negative charge can only attract each other, and can not be combined), so that the potential difference has been there until you To discharge, the bipolar plate with a wire, the electrons along the wire from the lower plate to move to the upper plate, the potential difference disappeared.
- Q:What is the difference between polyester film capacitors and ceramic capacitors?
- Polyester capacitor medium for the polyester film, its capacity and pressure range, small size, large capacity, high temperature, low cost. But tgδ with the frequency changes, it is used for tgδ, stability and loss requirements are not high occasions, such as DC and pulsating circuit.
- Q:How to use the capacitor
- High temperature no load test test, high temperature and high humidity load test, temperature jerk test and so may lead to increased leakage current. Therefore, do not apply solid-state aluminum capacitors to leak-current-sensitive circuits
- Q:Use capacitance to do transformer how to calculate
- Similarly, we can also 5W / 65V bulb and 1uF capacitor series connected to the 220V / 50Hz AC, the bulb will be lit, and will not be burned. Because the 5W / 65V bulb operating current is also about 70mA. Therefore, the capacitor buck is actually using capacitive current limiting. While the capacitor actually functions as a limiting current and dynamically distributes the voltage across the capacitor and the load.
- Q:Capacitance can pass high frequency resistance low frequency principle
- This process of current flow will soon end, the specific length of time and the resistance of the circuit and the size of the capacitor, the larger the size of the product the greater the charging time, the shorter the contrary. After charging is complete, the voltage across the capacitor is equal to the size of the DC supply voltage
- Q:Low voltage capacitor voltage 0.45 and 0.4 What is the difference between usage
- 0.45 capacitor used in the voltage level is high (for example, the transformer low voltage side voltage may reach 415V), with a tuned reactor (tuning reactor will increase the capacitor terminal voltage) situation; Note that the actual capacity of 0.45 capacitor nominal capacity (Actual voltage / 0.45) ^ 2 times;
- Q:Cd capacitance to express what
- Mainly speaking, the winding process of the capacitor is a non-inductive winding structure (relative, there is a sense of winding structure), in fact, no sense of capacitance is not no inductance, but the inductance is very small, for high-frequency operation of the capacitor, We emphasize no sense. In fact, the inductance is small. From this point of view, almost all of the metal film capacitors are no sense
