1413 CAPACITANCE DECADE BOX

1413 Series 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. The lower four decades contain adjustments that are factory set but accessible for readjustment later if desired.

• 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.
