What is the temperature coefficient of a mica capacitor?
The average temperature coefficient is around 50 ppm/°C. Mica capacitors have low resistive and inductive losses (high Q factor). Their characteristics are mostly frequency-independent, which allows for their use at high frequency. These superior characteristics come at a price: silver mica capacitors are bulky and expensive.
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%.
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.
