No coating material or "Lock Paint" (locking sealant) shall be applicable. Do not apply any adhesive such as "Lock Paint" to the adjustable part (rotor) of the fine-tuned capacitor. In some applications, a wide area of the circuit board can be coated with resin or rubber protective materials to impr

Use of appropriate screwdriver according to the slot on the fine-tuning capacitor. When an inappropriate or worn top screwdriver is used, it may be difficult to adjust the capacitance value. Similarly, due to the effect of stray capacitance, use of screwdriver with tip as metal will also increase th

Air conditioning capacitor insertion method is not fastidious, as long as the two ends of the corresponding two phases of the motor can be added. 1. Ac electrolytic capacitor or polypropylene, polyester capacitor used to start single phase asynchronous motor. 2. Capacitive induction motor has two wi

When there is no suitable capacitance replacement, the series and parallel capacitors can be used to obtain the appropriate capacitance. If the voltage value of the capacitance is not enough, the series method can also be used to improve the voltage value. If the circuit needs more than 25V voltage,

Mica capacitance, ceramic capacitor can be replaced by paper capacitance. Ceramic dielectric capacitance can be replaced by mica capacitor and glass-glazed capacitor. Tantalum electrolytic capacitance can be replaced by aluminum electrolytic capacitor.

The rated voltage of the substitute capacitor must be greater than or equal to the rated voltage of the original capacitance or greater than the operating voltage of the actual circuit. The frequency characteristic of the substitute capacitor must meet the frequency requirement of the actual circuit

Fixed capacitance is prone to fault phenomena such as leakage, short circuit, open circuit, inadequate contact of the internal lead of the capacitor (the connection between the pole and the lead) and so on. Especially the electrolytic capacitance, its failure rate is much higher than other

The energy storage capacitor collects the charge through the rectifier and transmits the stored energy through the converter lead to the output of the power supply. Aluminium electrolytic capacitors rated 40V 450VDC with a capacitance between 220U 150000uF (e.g., EPCOS B43504 or B43505). Is more com

By-pass capacitance is a kind of energy storage device which can provide energy for local devices. It can make the output of voltage stabilizer uniform and reduce the load requirement. Like small rechargeable batteries, bypass capacitors can be charged and let off the device. To minimize impedance,

Filtering is an important part of capacitance. Almost all power circuits are used. Theoretically (that is to say, the capacitance is assumed to be a pure capacitance), the larger the capacitance, the smaller the impedance and the higher the passing frequency. However, in fact, most of the capacitors
