Suntan Silver mica capacitors
Silver mica capacitors, also known as silvered mica capacitors, rendered traditional mica capacitors obsolete. Instead of being clamped with foils these use sheets of mica coated on both sides with deposited metal. The assembly is dipped in epoxy. The advantages are:
1.greater stability, since there are no capacitive airgaps that can change dimension
2.airtight enclosure removes the risk of oxidation or corrosion of plates or connections.
3.greater capacitance per volume, since
- there are no airgaps between plates and mica,
- the conducting surfaces can be thinner.
- no clamping mechanism is needed
