The capacitance, dissipation factor and Q should be measured
at 20˚C with 1±0.1kHz (char. SL: 1±0.1MHz) and AC5V(r.m.s.)
max.
The insulation resistance should be measured with
DC500±50V within 60±5 sec. of charging.
The voltage should be applied to the capacitor through a
resistor of 1MΩ.
The capacitor should not be damaged when test voltages of
Table 1 are applied between the lead wires for 60 sec.

8 Solderability of Leads
Lead wire should be soldered with uniform coating
on the axial direction over 3/4 of the circumferential
direction.
*¹ "C" expresses nominal capacitance value (pF).
The lead wire of a capacitor should be dipped into molten
solder for 2±0.5 sec.
The depth of immersion is up to about 1.5 to 2.0mm from the
root of lead wires.
Temp. of solder: Lead Free Solder (Sn-3Ag-0.5Cu) 245±5°C
H63 Eutectic Solder 235±5°C
