CH-12 single-value standard capacitor

  1. CH-12 standard capacitor has four BNC terminal connectors to output. The case is made from aluminum alloy. It has a small volume and is convenient to use.
  2. CH-12 series of standard capacitors have wide capacitance range, including eleven individual standard capacitors: 0.1pF, 1pF, 10pF, 100pF, 1nF, 10nF, 100nF, 1μF, 10μF, 100μF, and 1000μF. 0.1pF, 1pF and 10pF are quartz capacitors or air capacitors; 100pF, 1nF, 10nF and 100nF are mica capacitors or ceramics capacitors; and 1μF, 10μF, 100μF and 1,000μF are ceramics capacitors or composite dielectric capacitors. All of them are manufactured through special technical processing and treatment for long-term  stability .
  3. This series of standard capacitors is suitable for verifying and calibrating Class-0.05 and Class-0.5 four-terminal capacitance measurement instruments, and can be easily converted into three-terminal outputs.
