Aluminum electrolytic capacitors are the most common and polarized capacitors. Let’s discuss what affects the leakage current of aluminum electrolytic capacitors. 1.1 Leakage current and its characterization parameters When a constant DC voltage is applied across the capacitor, its charging current starts to be very large and gradually decreases over time. However, the decline will not [...]
In the world of electronics, circuit diagrams serve as the universal language of communication for engineers, technicians, and hobbyists alike. These diagrams represent the intricate connections and components within electronic circuits, facilitating understanding and analysis. At the heart of every circuit diagram lies a series of symbols that represent various electronic components, each with its own [...]
🍏The configuration of AC and DC capacitor filters in the converter station is mainly based on the harmonic components and reactive power requirements of the AC and DC sides of the converter station, and the configuration of the parallel capacitors is based on the reactive power requirements of the AC side of the converter station. During [...]
The dense air cargo routes between China and Europe outline the beautiful arc of the "Air Silk Road". Affected by the new crown epidemic, many European countries have closed "non-essential" physical stores. For a time, online shopping from China became a new consumer fashion. Liege Airport in southern Belgium is the largest airport in terms of [...]
Safety capacitor detection method.Safety capacitor is a kind of capacitor that will not affect the human body even if it fails. Because of its high performance, it has become a advertised product among capacitor products and is highly favored. However, testing is an indispensable process for the purchase or use of safety capacitors. Once there are [...]
Military DC high voltage ceramic capacitors use DC voltage as the working voltage, which is often more stringent than civilian ones. There will be clear indicators in all aspects, mainly in the following aspects: 1. Tinned layer; 2. Lead or screw lead; 3. Loss angle; 4. Capacity deviation; 5. Temperature shock and voltage treatment (voltage-temperature limit); [...]
Working together to fight the epidemic has given China and ASEAN a strong momentum for cooperation. Since the outbreak of the new crown pneumonia, China and ASEAN countries have always maintained close cooperation. While working together to fight the epidemic, they have promoted economic and trade exchanges. Bilateral relations have shown strong endogenous momentum. Recently, at [...]
The first characteristic of SMDcharacteristics electrolytic capacitors : the capacitance per unit volume is very large, which is tens to hundreds of times larger than other types of capacitors. SMDcharacteristics electrolytic capacitors two: rated capacity can be very large, can easily achieve tens of thousands of μf or even a few f (but can not be [...]
