Suntan Silver Mica Capacitors with high reliability (SM tradmark)

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 requence 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:

• greater stability, since there are no capacitive airgaps that can change dimension,
• airtight enclosure removes the risk of oxidation or corrosion of plates or connections.
• greater value per volume, since
• there are no airgaps between plates and mica,
• the conducting surfaces can be thinner.
• no clamping mechanism is needed

Variable capacitors are mostly used in radio tuning circuits and they are sometimes called 'tuning capacitors'. They have very small capacitance values, typically between 100pF and 500pF (100pF = 0.0001µF). The type illustrated usually has trimmers built in (for making small adjustments - see below) as well as the main variable capacitor.

Many variable capacitors have very short spindles which are not suitable for the standard knobs used for variable resistors and rotary switches. It would be wise to check that a suitable knob is available before ordering a variable capacitor.

Variable capacitors are not normally used in timing circuits because their capacitance is too small to be practical and the range of values available is very limited. Instead timing circuits use a fixed capacitor and a variable resistor if it is necessary to vary the time period.
