Choose solid capacitor or liquid capacitor for computer motherboard?

Due to the long-term use of the computer motherboard, overheating causes the capacitor electrolyte to heat and expand, the capacitance loses its function, and even exceeds the boiling point, causing the capacitor to expand and burst. So is it better to choose solid capacitor or liquid capacitor for computer motherboards? When the computer motherboard is not [...]

What is a coupling capacitor?

coupling capacitor, also known as electric field coupling or electrostatic coupling, is a coupling method due to the existence of distributed capacitance. Coupling capacitors make the two systems of strong and weak currents coupled and isolated by capacitors, provide high-frequency signal paths, prevent low-frequency currents from entering the weak current system, and ensure personal safety. In [...]

Classification of variable capacitors

Variable capacitors can be divided into air dielectric variable capacitor and solid dielectric variable capacitor according to their dielectric materials. 1. Air dielectric variable capacitor The electrode of the air dielectric variable capacitor is composed of two sets of metal sheets. Among the two sets of electrodes, the fixed set is the stator, and the rotatable [...]
