6 FAQs about [Mica adjustable capacitor]
Why is mica a good capacitor?
As a dielectric, mica provides capacitors with stable, highly accurate capacitance values. Mica capacitors exhibit low losses, which means they have a high quality factor (Q) and low dissipation factor (DF). For an explanation of these terms, read: The engineer’s capacitor glossary: All terms and acronyms defined.
What is a good replacement for mica capacitors?
In low power RF applications, a good replacement for mica capacitors are ceramic capacitors. If capacitance tolerances and low losses are an important factor, Class 1 ceramic capacitors can be used, since these capacitors have similar tolerances at a fraction of the price.
What is a silver mica capacitor?
Silver mica capacitors are generally used for applications where only a small level of capacitance is required. They tend to range between low levels such as a few pF, up to low levels of nF. Silver capacitors are typically rated for voltages that range between 100 volts up to 1000 volts.
What are the different types of mica capacitors?
There are two different types of mica capacitors: silver mica capacitors and clamped mica capacitors. We no longer use clamped mica capacitors in electrical systems and circuits and they are now seen as obsolete components. This is because silver mica capacitors have much better characteristics than clamped mica capacitors.
Can mica capacitors be used in high-frequency applications?
Mica capacitors are also classified as low-loss capacitors, this means that they can be used in high-frequency applications as they are stable and their values do not differ much over time. Silver mica capacitors are generally used for applications where only a small level of capacitance is required.
What is the maximum capacitance of a mica capacitor?
The largest capacitance mica capacitors can reach values of 1µF, although these are uncommon. Silver mica capacitors are usually rated for voltages between 100 and 1000 volts, although there are special high-voltage mica capacitors designed for RF transmitter use which are rated at up to 10 kV.
