1. The larger the capacitance, the better.Many people prefer to use large capacity capacitors in the replacement of capacitors. We know that the larger the capacitance, the stronger the ability to compensate for the IC's current. Not to mention the increase of capacitive capacity will increase the v

Frequency characteristic analysis: Frequency characteristic analysis is mainly used to analyze whether the frequency of the circuit itself is suitable for the frequency of the signal it processes. In the analysis, the center frequency, upper and lower limit frequency and frequency bandwidth shoul

Time constant analysis:The time constant analysis method is mainly used to analyze the properties of the circuit composed of R，L，C and semiconductor diode. The time constant is a parameter reflecting the energy accumulation rate of the energy storage element, if the time constant is different. Altho

AC equivalent circuit analysis：Ac equivalent circuit analysis is one way to separate the AC system from the circuit and analyze it separately. In AC equivalent analysis, the AC equivalent circuit diagram should be drawn first. The following principles should be followed in drawing the AC equivalent

DC equivalent circuit analysis:When analyzing the principle of the circuit, it is necessary to find out the DC path and the AC path in the circuit. DC path refers to the static bias of each semiconductor transistor and integrated circuit when there is no input signal.That is, their static operating

We have a precise understanding of the role of air conditioning capacitors, hope to be able to help the majority of maintenance personnel. I hope I can help you solve some problems with capacitors.The reliability of capacitors depends not only on the reliability of the capacitors themselves. And is

Capacitor detection methods are divided into three main categories: variable capacitor detection, electrolytic capacitor detection, fixed capacitor detection. Detection of variable capacitors A .with the hand gently rotates the axis, should feel very smooth, should not feel sometimes lose when tigh

Detection of fixed capacitors A .Detection of small capacitors below 10pF because the capacity of fixed capacitors below 10pF is too small to be measured with a multimeter, it can only be qualitatively checked whether it has leakage, internal short circuit or breakdown phenomenon. In the measurement

Detection of electrolytic capacitors A .Because the capacity of electrolytic capacitance is much larger than that of ordinary fixed capacitance, therefore, when measuring, we should choose suitable measuring range for different capacity. According to the experience, the capacitance between 47 μ F an

Air conditioning has become an indispensable necessity in people's life. With the popularization of air conditioning has expanded the scope of use, air-conditioning capacitance, all kinds of air conditioning failure are also increasing. Today share with you is a part of the air conditioning, the rol
