LOW TEMPERATURE BEHAVIOUR

Table for the calculation of the maximum 10 kHz impedance at low temperatures:

The lower limit of the series resistance and impedance is determined by the ohmic part of the contact points and the foil

resistance values. Therefore it will not always be possible to achieve calculated values below 0.05

.

Note

I

User current [A]

L

Lifetime multiplier

Regard L as a function of ambient temperature (x-axis) and of current (y-axis); use the current-axis according to the frequency
