Tips of vacuum capacitors:

Vacuum capacitors are designed to meet MIL-C-23183 specifications. Based uponactual current tests, most ceramic capacitors are rated for a maximum operatingtemperature of 120°C (250°F) and glass capacitors for 87°C (188°F) with normalconvection cooling at an ambient temperature of 25°C (72°F). Derating curves for elevated ambient temperature operation are available upon request.

Fixed capacitors with a nominalcapacitance above 50 pF shall be within ±5 %. Capacitors with a nominalcapacitance of 50 pF or less shall be within ±10%, or .5 pF, whichever isgreater. For variable capacitors, the low end will be equal to or less thanminimum rating. The capacitance change is substantially uniform with rotation,and there are no capacitance reversals. Capacitance is within ±10% of thenominal value of the curves shown (Capacity vs. Turns), when the turns settingfor reference purposes (defines point) is established near the low capacity endof the linear portion of this curve.
