DEJ Series (Which Meet Japanese Law) Specifications and Test Methods
Continued on the following page.
The lead wire of a capacitor should be dipped into molten
solder for 2
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
H63 Eutectic Solder 235
Solderability of Leads
Lead wire should be soldered with uniform coating
on the axial direction over 3/4 of the circumferential
As in Figure 1, discharge is made 50 times at 5 sec. intervals
from the capacitor (Cd) charged at DC voltage of specified.
Ct: Capacitor under test
S: High-voltage switch
R3: Surge resistance
No marked defect
Per Item 6
The capacitance measurement should be made at each step
specified in Table 1.
The capacitor should not be damaged when AC1500V(r.m.s.)
are applied between the lead wires for 60 sec.
First, the terminals of the capacitor should be connected
together. Then, as shown in the figure at right,
the capacitor should be immersed
into 10% salt solution up to a position
of about 3 to 4mm apart from the
Finally, AC1500V(r.m.s.) is applied
for 60 sec. between the capacitor lead
wires and electrode plate.
The insulation resistance should be measured with
±50V within 60±5 sec. of charging.
Insulation Resistance (I.R.)
The dissipation factor should be measured at 20˚C with
±0.1kHz and AC5V(r.m.s.) max.
The capacitance should be measured at 20˚C with 1
and AC5V(r.m.s.) max.
Within specified tolerance
The capacitor should be visually inspected.
To be easily legible
The capacitor should be visually inspected for evidence of
Dimensions should be measured with slide calipers.
Appearance and Dimensions
No visible defect, and dimensions are within
Operating Temperature Range: -25 to +85
3 to 4mm
10% Salt Solution
