What should I do if the capacitor is broken? Many people will have this question. The capacitor on my circuit board is broken, but I don't know what its capacity is. What should I do if I change it to a larger one?
The best way to solve the problem is to replace the capacitor with the same capacity in smt factory. Because there are few capacitors, many of them are not marked with their capacity. Generally, the whole disk is marked with it. How do you see the capacitance of an electric patch? In the process of patch processing, it needs to be tested with a tester. If it is the same factory logo, the capacity of dark color will be larger than that of light color, and brown gray is greater than light purple and gray. The best way is to measure with a capacitance meter.
Capacitance measurement method:
Capacitors in smt chip processing plants are ceramic capacitors, which need to be produced at high temperature, so there is no value marked on them. Capacitors are generally divided into three situations: leakage and breakdown or no capacitance. If it is detected, use a multimeter to detect the resistance and adjust it to 10K-20K as the standard measurement, especially the smt chip capacitance. The pen tip of the meter to be used is on both sides of it. If its value is rising, it means it is good, but the capacitance value is 0, which means it has no capacity or is broken.
