The 1413 Capacitor Decade
Decade Capacitor are made to the same exacting specs as GenRad.
The 1413 Capacitance Decade is not only a capacitance precision standard, it is a systems component as
well - connections are made at the rear for this purpose.
Six precision decades are employed to provide a range of 0 to 1.11111µF in increments as small as
1 pF
and with an accuracy of 0.05% +0.5pF. Air capacitors are used for the two lower decades and precision
silvered-mica capacitors are used for the remainder.

0 to 1.11111 µF
0.05% + 0.5 pF basic accuracy
Step 1 pF
6-digit resolution
3-terminal connections
Optional rear-mounted GR-874 locking connectors.
The shielding is divided into two parts, arranged to provide low terminal-to-guard capacitances.
When the two shields are connected together, the 1413 becomes a well-shielded three-terminal capacitor
with an extremely low zero-capacitance, suitable for a variety of applications.
