6 FAQs about [Capacitor high and low temperature screening standards]

How difficult is it to calibrate capacitors for use as standards?

Selection and calibration of capacitors for use as Standards is a challenging task, especially since the accuracies required, depening on the application, can be very demanding for the test gear as well as for the secondary- and working-standards used.

What are the test severities for a capacitor?

Test severities for capacitor volumes above 12,000 mm3 are under consideration. Unless otherwise specified in the detail specification, DC voltage of an amplitude necessary to produce a current of 10 mA/F or more shall be applied to the capacitor in the forward direction.

How long should a capacitor be tested?

At these parameters of the model the acceleration factors are large, and a 96-hour testing of capacitors at 2 times rated voltage (VR) and 125 °C during voltage conditioning (a typical screening procedure) would be equivalent to testing at operating conditions (assumed 50 °C and 0.5 VR) to more than a thousand years of operation (see Figure 1).

What is the test UC for a capacitor?

The capacitors shall be subjected to IEC 60068-2-21, Test Uc, as applicable. Method A, severity 2 (two successive rotations of 180°) shall be used. This test shall not apply is in the detail specification the terminations are described as rigid and to components with unidirectional terminations designed for printed wiring applications.

What PLE current rating should a capacitor have?

Which gr1403 capacitors are calibrated to 133 ppm?

Consequently, the GR1403 capacitors used for the calibration/verification of our IET1689 digibridge have this uncertainty (plus the related temperature drift uncertainty for a +/-2K temperature uncertainty; normal distribution). Thus, these capacitors are calibrated to 133ppm or 0,0133% worst case.
