The normal working range for most capacitors is -30 o C to +125 o C with nominal voltage ratings given for a Working Temperature of no more than +70 o C especially for the plastic capacitor types.
All Kendeil capacitors maintain good behaviour under any climatic conditions when operating conditions are within the design specifications limits of each product type. Since each capacitor is hermetically sealed, the wet element inside impregnated with electrolyte will not be exposed to external conditions such as high pressure or vacuum.
Changes in temperature around the capacitor affect the value of the capacitance because of changes in the dielectric properties. If the air or surrounding temperature becomes to hot or to cold the capacitance value of the capacitor may change so much as to affect the correct operation of the circuit.
The temperature rise of the core is directly proportional to the core-to-ambient thermal re-sistance, and this paper models this thermal resistance for various capacitor construction techniques. Results are adapted for use in a new, lumped-parameter model suitable for use in a spreadsheet or a Java applet.
However it is advisable to dry immediately with hot air, which is best achieved at 85°C for few minutes. After having a capacitor exposed to high temperatures such as direct sunlight or heating elements, the capacitor life may be adversely affected.
Calculating the thermal resistance of (30) a capacitor mounted to a chassis. (37) Fig. 4 shows a typical temperature distribution plot. The = (T(0) - TA)/P . and extend the life of the capacitor. capacitor. ture change needs to be evaluated. The thermal time ent temperature. Once the effective thermal resistance hL / k « 1 .
In use, the working voltage or its operating temperature range corresponding to its de-rating curve should never be exceeded, nor should the capacitor''s polarity be reversed. Then please consult the capacitors datasheet for more information.
