In electronic equipment, the alternating current output from a device often has high-frequency components and low-frequency components. At this time, the high frequency bypass capacitor can filter high frequency (let the high frequency pass through the branch where the high frequency bypass capacitor is located) and retain the low frequency (low frequency output). The capacitor that [...]
New Foreign Trade Regulations in September, See which changes are closely linked to us. ♦ The EU extends the policy of “suspending the collection of import duties and value-added tax on medical supplies” On July 27, the EU revised its decision to suspend the collection of tariffs and value-added taxes on imported medical supplies, extending the [...]
The biggest feature of the self-healing shunt capacitor is its self-healing performance. When the dielectric breaks down, the short-circuit current will melt and evaporate the metal film around the breakdown site, thereby restoring the insulation, so it has a higher operational reliability. The self-healing time after dielectric breakdown is only a few microseconds. When the weak [...]
The Sino-US economic and trade talks are harmonious and smooth. The two sides agreed to continue to promote the implementation of the first phase of the economic and trade agreement. On the morning of August 25th, Liu He, member of the Political Bureau of the CPC Central Committee, Vice Premier of the State Council, and the [...]
A fixed capacitance is a capacitor with a fixed capacitance. The deviation of the actual capacitance of the capacitor from the nominal capacitance is called the error, and the tolerance is called the accuracy.Selection method of fixed capacitor: (1) Choose the model reasonably according to the requirements of the circuit Generally used in low frequency coupling [...]
