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 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.
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.
How do mica-metal capacitors work?
When aluminum and copper were substituted with silver, the performance of mica-metal capacitors increased. Thin sheets of mica separated by thin sheets of silver were stacked to form an assembly in these clamped mica capacitors. Before connecting the mica-silver layers, they were clamped.
What are mica capacitors made of?
Mica capacitors in the past were made from thin sheets of mica covered with thin sheets of silver. Although the thin layers were secured and electrons were supplied, there were small air gaps that harmed the accuracy of clamped mica capacitors owing to physical flaws in both layers.
What is a clamped mica capacitor?
Old clamped mica capacitors used thin sheets of mica layered with thin sheets of silver. These layers were clamped and electrodes were added. However, due to physical imperfections in both mica and silver layers, there were small air gaps present which limited the precision of clamped mica capacitors.
