"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 values Length of capacitor VR V DC 2500 4000 6300 k0 values Length of capacitor VR V DC 2500 4000 6300 VRMS V AC 220 220 220 k0 in V2/µs 125 000 320 000 62 500 160 000 500 000 33 mm 45 mm VRMS V AC 220 220 220 dV/dt in V/µs 25 40 12.5 20 40 33 mm 45 mm Please read Cautions and warnings and Important notes at the end of this document.

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.
