Suntan Silver Mica Capacitors with high reliability

Mica is one of the oldest dielectric mineralmaterials used in capacitor construction, with very stable electrically, mechanically and chemically. It has a dielectric constant in the range 5–7. Natural mica contains many other materials including, iron, sodium, ferric oxide, and lithium. Because of the variability in composition of natural mica, mica destined for use in capacitors must be carefully inspected and classified, which adds to the manufacturing cost.

Suntan Silver Mica Capacitors are available with values that range from 1–22,000 pF, voltages are in the range 50–1000V for standard dipped mica capacitors. Mica capacitors exhibit very little voltage dependence, have high Q or conversely small power factors that are quite independent of frequency. With all these advantage, our mica capacitors are ideal for high frequence and RF applications.

Silver Mica Capacitors Knowledge

Silver mica capacitors are high precision high stability high reliability capacitors. They are available in small values, and are mostly used at high frequencies.

Mica capacitors, which are now obsolete, were in use in the early 20th century. They consisted of sheets of mica and copper foil sandwiched together and clamped.

Silver mica capacitors, also known as silvered mica capacitors, obsoleted mica capacitors. 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 value per volume, since
  1. there are no airgaps between plates and mica,
  2. the conducting surfaces can be thinner.
  3. no clamping mechanism is needed

Silver mica capacitors are one of the less popularly used types because of price. Example prices:

  1. 100pF £0:99
  2. 10nF 1% silver mica £4:40
