Pulse handling capability
"dV/dt" represents the maximum permissible voltage change per unit of time for non-sinusoidal
voltages, expressed in V/µs.
Note:
The values of dV/dt provided below must not be exceeded in order to avoid damaging the
capacitor.

1 Soldering
1.1 Solderability of leads
The solderability of terminal leads is tested to IEC 60068-2-20, test Ta, method 1.
Before a solderability test is carried out, terminals are subjected to accelerated ageing (to
IEC 60068-2-2, test Ba: 4 h exposure to dry heat at 155 °C). Since the ageing temperature is far
higher than the upper category temperature of the capacitors, the terminal wires should be cut off
from the capacitor before the ageing procedure to prevent the solderability being impaired by the
products of any capacitor decomposition that might occur.
Solder bath temperature 235 ±5 °C
Soldering time 2.0 ±0.5 s
Immersion depth 2.0 +0/0.5 mm from capacitor body or seating plane
Evaluation criteria:
Visual inspection Wetting of wire surface by new solder ≥90%, free-flowing solder
1.2 Resistance to soldering heat
Resistance to soldering heat is tested to IEC 60068-2-20, test Tb, method 1A.
