HACS-Z Series High Accuracy Decade Capacitance Box

  • Product No:HACS-Z Series
  • Manufacturer:IET LABS, Inc.

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.

  • Connection to capacitor:  Two bnc connectors labeled HI and LO are located on the front panel.


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.
