CAPACITORS, FIXED, MICA DIELECTRIC, GENERAL SPECIFICATION FOR
|Publication Date:||31 July 2017|
This specification covers the general requirements for molded and dipped mica dielectric, fixed capacitors intended primarily for use in high-stability, low-loss radio-frequency applications such as tuned circuits (see 6.1). This is a graded specification covering ranges in temperature coefficient, capacitance, tolerance, temperature, and vibration.
These mica capacitors, because of their low-power factor, high-breakdown voltage, lowdielectric absorption, and high-insulation resistance, are intended for use in high-frequency circuits where... View More
These mica capacitors, because of their low-power factor, high-breakdown voltage, lowdielectric absorption, and high-insulation resistance, are intended for use in high-frequency circuits where good stability is required for temperature, frequency, and aging, such as in timing and frequency-determinin
Safe operating voltages. The voltage ratings specified (see 3.1) apply over the operating temperature range of the capacitor, and under the following conditions:
a. Barometric pressure: As specified in the associated specification sheet for altitudes up to 50,000 feet for the larger transmitting styles and 100,000 feet for the remaining styles.
b. Relative humidity: Up to 80 percent.
Flammability. It should be noted that this specification contains no requirements concerning the flammability of the materials used in the construction of the capacitors. Users should take this into consideration when a particular application involves this requirement.
Dissipation factor. For dissipation factor measurement purposes Q = 1/DF (see 3.8).View Less
