STANDARD CAPACITOR

The GenRad 1409 Standard Capacitor series offers highly stable cost-effective capacitance standards with low-temperature coefficient, low losses and a wide range of values. Up to 1 µF, the standard capacitors are constructed of fixed mica capacitors of very high stability for use as two- or three-terminal reference or working standards in the laboratory. From 1 µF to 10 µF the units are made of hermetically sealed polystyrene for 10 μF. Above 10 μF the capacitor is hermetically sealed polycarbonate.

Typical capacitors, observed over decades, have shown random fluctuations of less than + 0.01% in measured capacitance with no evidence of systemic drift.

The capacitors are made out of ≤1 µF silvered-mica and foil, spring-held in a heavy metal camp for mechanical stability. The units are selected for low dissipation factor and are stabilized by heat cycling. They are housed in cast aluminum cases, along with silica gel, which provides continuous dessication. These cases are sealed with high-temperature wax. A well is provided in the wall of the case for insertion of a dial-type thermometer. Three jack-top binding posts are provided on the top of the case, and removable banana plugs on the bottom, for convenient parallel connection without error

A well is provided in the wall of the case for insert­ing a dial-type thermometer. For convenient parallel connection without error, three jack-top binding posts are provided on the top case, with removable plugs on the bottom.

Features:

  • Two and Three terminal calibration provided
  • Available in 0.001µF, 0.01µF, 0.1µF, and 1.0µF
  • +0.01%/year stability
  • Calibration accuracy +0.02%
  • Values 0.001 µF (100 nF) to 1000 µF
  • Stability as good as ±0.01 %/year
  • Series Inductance: for 0.01 μF - 1 μF: typically < 0.06 μH
  • Series Resistance
  • For 0.01 μF - 0.1μF: 0.02 Ω
  • For 1 μF: 0.03 Ω
  • Two-to-five terminal configuration, depending on model
  • Leakage Resistance: 5,000 ohm-Farads or 100 GΩ, whichever is less
  • Calibration accredited to ISO-17025 included
