The characteristics and application of the mica capacitor
In the electronic products and mechanical equipment we use, we will use capacitors, such as mica capacitors, which are widely used. Let's take a look at the characteristics of the mica capacitor and the fields in which the mica capacitor can be applied?
What are the characteristics of the mica capacitor
Mica capacitor is one of the high-frequency capacitors, which is widely used in the occasions with high requirements for the stability and reliability of capacitors. Small size, lightweight, firm structure, convenient installation, and stable performance. It can be used in radio receiving and transmitting equipment, precision electronic instruments, modern communication instruments and equipment, radio, power amplifier, television. Mica capacitor is a kind of electrode plate made of metal foil or spraying silver layer on mica. The electrode plate and mica are laminated ones by one, then die-casting in bakelite powder or sealed in epoxy resin. It is characterized by small dielectric loss, large insulation resistance, and a small temperature coefficient, so it is suitable for a high frequency circuit.
What fields can mica capacitors be used in
In the insulation support materials and dielectric materials of capacitors and motors, mica flakes have been replaced by mica paper made of mica flakes, and most communication electronic tubes have been replaced by semiconductor integrated circuits. Mica has high electrical insulation, good transparency, excellent peelability, high chemical stability, good reproducibility, and can maintain the above excellent physical and chemical properties at high temperatures. Therefore, mica is mainly used as a very important insulating material in electronics, motors, telecommunications, electrical appliances, aviation, transportation, instruments, metallurgy, building materials, light industry, And other industrial sectors, as well as defense and cutting-edge industries.
Mica capacitor belongs to a high-frequency capacitor, its stability and reliability are very high. Mica capacitor has the characteristics of small volume, lightweight, and firm structure, and it is very convenient to install.
