The 4278A 1 kHz/1 MHz capacitance meter is a high-speed, highly reliable, precision test instrument aimed at incoming/outgoing capacitor inspection applications on the production line and in quality control. The 4278A will improve test efficiency by performing comparative measurements of low to medium value capacitors(up to 200 F – a range that covers most ceramic and film capacitors). The 4278A’s standard measurement frequencies and oscillator output level are 1 kHz/1 MHz and from 0.1 V to 1 V in 0.1 V steps, respectively.The built-in comparator function of the 4278A gives you the ability to sort parts into ten bins. A high-speed HP-IB interface and an optional handler interface are available fir combining the 4278A with an automatic handler and an external computer, to build a total solution for automatic testing and data acquisition and analysis.

  • Measurement speed: 6.5 ms/10 ms/21 ms
  • Measurement parameters: C-D, Q, ESR, G
  • C-D measurement accuracy: 0.07%, 0.0005(1 kHz, 21ms);.0.5%, 0.0002(1 MHz, 21 ms)
  • High resolution: 6 digit, D:0.00001
  • Intelligent built-in comparator: 10-bin sorting
