6 FAQs about [Capacitor temperature measurement brand]
Can a capacitor temperature be measured with an electrical measurement?
The capacitor temperature can also be measured with an electrical measurement but it needs to be considered that selecting the appropriate temperature dependent electric parameter is a key for the good measurement results.
What determines the operating temperature of a capacitor?
The operating temperature of the capacitors, just like that of other components depends on the environment, i.e. on one hand on the heating of the surrounding components, on the other hand on the internal heat generation of the device itself.
What temperature should a capacitor be calibrated?
In case of the capacitor component where the heat is mostly generated in the core volume the validity of this approximation is questionable, but it has only a minor effect on the final results. The calibration was done between 20°C and 95°C in 5°C steps. The resulting calibration points are shown in Figure 8.
How does ambient temperature affect the endurance of an aluminum electrolytic capacitor?
The endurance of an aluminum electrolytic capacitor is affected by the ambient temperature, and a decline of 10°C in the ambient temperature will increase capacitor endurance by two-fold (the 10°C half-life rule). Accurately measuring the ambient temperature is critical to product lifetime estimation.
Does a thermal transient measure a capacitor?
The thermal transient measurement of the capacitor provided realistic transient curves, and the effect of the change of pin length could also be clearly identified. However the validity of the curve still needs to be proven.
