GenRad 1403 Series High Frequency Standard Capacitor Basic Specifications
Calibration: A certificate of calibration is supplied with each unit giving the measured capacitance at 1 kc/s and at a specified temperature. The measured value is the direct capacitance between shielded terminals when the capacitor has at least one lead completely shielded and its case connected to a guard point.
This value is obtained by comparison, to a precision better than ±(0.01% + 0.00001 pF), with working standards whose absolute values are known to an accuracy typically ±0.01%, determined and maintained in terms of reference standards periodically certified at NIST
Stability: Capacitance change is less than 0.05% per year.
Temperature Coefficient of Direct Capacitance: Typically 20 to 40 ppm per degree between 20° and 70°C. The larger coefficients apply to the smaller capacitance values.
Terminals: GR874 Coaxial Connectors, which provide complete shielding of the leads.
