Calibration: An certifi cate of calibration is supplied
with each capacitor traceable to the SI, giving the
measured direct capacitance and Df at
1 kHz, 15 Vac and 23° ±1°C.
Temperature Coeffi cient of Capacitance:
Typically ±(20 to 40) ppm/°C, between 20°C and
70°C
Stability: Capacitance change is less than 0.05% per
year.
Residual impedance: See equivalent circuit and plot
on page 1
Terminals: Two GR874 coaxial connectors
Two bnc-f connectors for 1403-1pF-BNC
Outer shell of connectors are connected to case
ground to provide complete shielding of the leads.
Mechanical:
Diameter 3.0625 in (78 mm), height 4.875 in (125
mm), over-all.
Net weight: 1 lbs (0.5 kg)
Shipping weight: 4 lbs (1.9 kg)
