"k0" represents the maximum permissible pulse characteristic of the waveform applied to the capacitor, expressed in V2/µs. Note: The values of dV/dt and k0 provided below must not be exceeded in order to avoid damaging the capacitor. dV/dt and k0 values VR (V DC) 2 500 4 000 6 300 8 000 10 000 12 500 VRMS (V AC) 200 450 450 450 450 450 dV/dt in V/µs 25 40 50 50 370 1000 k0 in V2/µs 125 000 320 000 630 000 800 000 7 500 000 25 000 000 Impedance Z versus frequency f (typical values) Permissible AC voltage VRMS versus frequency f Values can be obtained on request.

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 Soldering time Immersion depth Evaluation criteria: Visual inspection 1.2 235 ±5 °C 2.0 ±0.5 s 2.0 +0/ 0.5 mm from capacitor body or seating plane Wetting of wire surface by new solder ≥90%, free-flowing solder Resistance to soldering heat Resistance to soldering heat is tested to IEC 60068-2-20, test Tb, method 1A.
