What are mica capacitors?
Mica capacitors are the stable, reliable and high precision capacitors. These capacitors are available from low voltages to high voltages. The capacitance values of the mica capacitors ranging from 20 pF to 10 µF. Mica capacitors are mostly used in the applications where high accuracy and low capacitance change over the time is desired.
Can mica capacitors withstand high voltages?
Mica capacitors can withstand high voltages, operate at high temperatures and have low leakage current. Because mica capacitors have a very small inductive characteristic and low losses, they are often used in radio frequency (RF) circuits. Silver is used to form mica capacitor plates.
Are silver mica capacitors good?
They have great high-frequency properties due to low resistive and inductive losses, and are very stable over time. The minimum tolerance for silver mica capacitor values can be as low as ±1%. This is much better than practically all other types of capacitors. In comparison, certain ceramic capacitors can have tolerances of up to ±20%.
What are the disadvantages of mica capacitors?
One major drawback is their relatively large size compared to modern surface-mount capacitors, which can make them less suitable for compact or densely packed circuit designs. Additionally, mica capacitors are often more expensive due to the cost of mica as a dielectric material and the intricate manufacturing process involved.
How is a silver mica capacitor encapsulated?
After the layers are assembled, electrodes are added and the assembly is encapsulated. Ceramics or epoxy resins are used as encapsulation material in order to protect the silver-mica capacitor from outside effects such as moisture. Silver mica capacitors have a relatively small capacitance value: usually between a few pF, up to a few nF.
What are the tolerance levels of mica capacitors?
Silver mica capacitors can have tolerance levels of +/- 1%, this is extremely precise and why they are used in applications where precision is key. Mica capacitors generally have one of the lowest tolerance levels when compare to other types of capacitors. Some types of ceramic capacitors can have tolerance ranges of +/- 20%.
