If the electric fan capacitor uses 1.5UF or 2UF, it may be an AC fan, and this capacitor is the starting capacitor of the AC fan motor. If the power supply part is a resistor-capacitor step-down, it may be a capacitor used for step-down. Two capacitors are introduced separately. 1. If the resistance-capacitance step-down is used, [...]
MLCC is formed by stacking ceramic dielectric membranes with printed electrodes (inner electrodes) in a staggered manner. After a one-time high-temperature sintering to form a ceramic chip, the two ends of the chip are sealed with metal layers (outer electrodes). MLCC not only has the characteristics of capacitor "passing through and passing through", it also has [...]
Can capacitors of the same patch size be replaced? Capacitors of the same package cannot be distinguished from the appearance. The capacitors of 100nF and 1nF in the same package are difficult to distinguish from the appearance, although they may be different in thickness. 1. If the chip on the power side of the chip may [...]
Safety capacitors are safety capacitors that will not affect the human body even if they fail. They are favored because of their high safety expertise. However, for the purchase or use of safety capacitors, routine testing of safety capacitors is an indispensable process. 1. Rotate the shaft gently with your hands. It should feel very smooth, [...]
Characteristics and applications of through-core capacitors 1) Welded core capacitor Welded core capacitors are ideal for installations where space is tight; Application: Mainly used for filtering signals, data lines and AC power lines; Telecommunications equipment, transmission equipment, microwave filters, industrial computers, composite circuit filter components; Small size: effective use of space; Rated voltage: up to 1000VDC; [...]
