Mica capacitor is just casual reference to Silver Mica capacitor . Old style (pre 1930s) Clamp mica caps are obsolete because of poor stability and tolerance . Silver mica capacitors have a very low tolerance of around ±1% and have low resistive, inductive losses and have high Q-factor because of low thermal losses.
Mica-Capacitor Color Code. The electrical value of a mica capacitor can be determined from an examination of the six-dot color code imprinted on the body of the capacitor. When the capacitor is being read, the direction indicator (an arrow on the body in some form) should point to the right of the reader.

Mica or silver mica capacitors are a type of capacitor that uses mica as a dielectric. Mica is a very electrically, chemically, and mechanically stable material. Although it has the great characteristics of good electrical properties and high-temperature resistance, it has a high cost for raw materials.
Ceramic capacitors were also used in the 1920s due to a shortage of mica, but by the 1950s silver mica had become the capacitor of choice for small-value RF applications. This remained the case until the latter part of the 20th century when advances in ceramic capacitors led to the replacement of mica with ceramic in most applications.
