Description:
The HACS-Z Decade Capacitance System is capable of meeting exacting requirements for fixed or adjustable calibration capacitance or any applications requiring precise stable capacitance values. It provides a wide range of capacitance in increments as low as 1 pF and a total capacitance of up to 10,000 μF. With its high-quality, tight-tolerance capacitors, it is an ideal part of a test or calibration system.
Features:
• High accuracy: 0.05%
• Low zero capacitance: <0.1 pF
• Trimmable capacitors for lower decades
• 3-Terminal shielded construction for low values
• 5-Terminal construction for high values
• Excellent stability - 100 ppm/year
• Excellent TC - begins at 20 ppm/°C
SPECIFICATIONS: LOW VALUES
Zero capacitance: ≤0.1 pF maximum capacitance obtained with all dials set to zero
Temperature coefficient: <20 ppm/°C
Insulation resistance: >50,000 MΩ
Environmental conditions:
Operating conditions: 10°C to 40°C
Storage conditions: -40°C to 70°C
Shielding: Double-shielded construction ; see below.

SPECIFICATIONS: HIGH VALUES
Zero capacitance: ≤0.5 pF maximum capacitance obtained with all dials set to zero;5-terminal measurement
Temperature coefficient: -50 ppm/°C
Insulation resistance: >50,000 MΩ
Environmental conditions:
Operating conditions: 10°C to 40°C
Storage conditions: -40°C to 70°C
Connection to capacitor: Five 5-way binding posts labeled HI CURRENT, LO CURRENT, HI SENSE, LO SENSE and GND are located on the front panel. Special wiring and low-resistance conductors in this 4-terminal connection circuit minimize dissipation and parasitic inductance, and improve frequency characteristics. To use as a 2-terminal capacitor, connect to only the two SENSE terminals.
