The difference between series and parallel capacitors is: different composition, different current paths, and different disconnection. 1. Different composition 1. Series connection: Series connection is to connect the components one by one. 2. Parallel connection: Parallel connection consists of connecting components in parallel. Two, the current path is different 1. Series connection: In the series circuit, [...]
Due to the long-term use of the computer motherboard, overheating causes the capacitor electrolyte to heat and expand, the capacitance loses its function, and even exceeds the boiling point, causing the capacitor to expand and burst. So is it better to choose solid capacitor or liquid capacitor for computer motherboards? When the computer motherboard is not [...]
coupling capacitor, also known as electric field coupling or electrostatic coupling, is a coupling method due to the existence of distributed capacitance. Coupling capacitors make the two systems of strong and weak currents coupled and isolated by capacitors, provide high-frequency signal paths, prevent low-frequency currents from entering the weak current system, and ensure personal safety. In [...]
paper capacitors use special capacitor paper as the medium, aluminum foil or tin foil as the electrode and wound into a cylindrical shape, then connect the lead, and then pass the staining treatment, and it is made of shell packaging or epoxy resin potting. Its structure is shown in the figure. Paper capacitors have the following [...]
The lifetime of photovoltaic inverter is determined by the reliability of its components. Electrolytic capacitors are one of the key components to improve the reliability of photovoltaic inverters. In addition, photovoltaic inverters have high expectations for life, so there are also requirements for capacitors. Photovoltaic inverter requirements for electrolytic capacitors 1. High voltage Generally, high-power photovoltaic [...]
