DEC Series (Class1, 2 / DC6.3kV) Specifications and Test Methods
No.
1
Item
Operating Temperature Range
Specifications
-25 to +85°C
Test Method
2
Appearance and Dimensions
No visible defect, and dimensions are
within specified range.
To be easily legible
The capacitor should be visually inspected for evidence of
defect. Dimensions should be measured with slide calipers.
3
Marking
The capacitor should be visually inspected.

Body Insulation
No failure
No failure
The capacitor should not be damaged when DC voltage of
200% of the rated voltage is applied between the lead wires for
1 to 5 sec. (Charge/Discharge current
V50mA)
The capacitor is placed in the container
with metal balls of diameter 1mm so that
each lead wire, short circuited, is kept
about 2mm off the metal balls as shown in
the figure at right, and DC voltage of 1.3kV
is applied for 1 to 5 sec. between capacitor
lead wires and metal balls.
(Charge/Discharge current
V50mA)
5
Insulation
Resistance (I.R.)
The insulation resistance should be measured with
DC500±50V within 60±5 sec. of charging.

Capacitance
The capacitance should be measured at 20°C with 1±0.2kHz
(Char. SL: 1±0.2MHz) and AC5V(r.m.s.) max.
Within specified tolerance
Char. SL: 400+20C*2min. (30pF under)
1000 min. (30pF min.)
Char. B, E: 2.5% max.
Char. SL: +350 to -1000ppm/°C
(Temp. range: +20 to +85°C)
Char. B: Within ±10%
Char. E: Within +20/-55%
The dissipation factor and Q should be measured at 20°C with
1±0.2kHz (Char. SL: 1±0.2MHz) and AC5V(r.m.s.) max.
8
Temperature Characteristics
The capacitance measurement should be made at each step
specified in the Table.
Pre-treatment: Capacitor should be stored at 85±2°C for 1 hr., then placed at
room condition*1 for 24±2 hrs. before measurements. (Char. B, E)
9
Strength of Lead
Pull
Lead wire should not be cut off.
Capacitor should not be broken.
As shown in the figure at right, fix the body of
the capacitor and apply a tensile weight
gradually to each lead wire in the radial
direction of the capacitor up to 10N and keep
it for 10±1 sec.
Bending
Each lead wire should be subjected to 5N of weight and bent
90° at the point of egress, in one direction, then returned to its
original position and bent 90° in the opposite direction at the
rate of one bend in 2 to 3 sec.
10
Vibration
Resistance
Appearance
No marked defect
The capacitor should be firmly soldered to the supporting lead
wire and vibrated at a frequency range of 10 to 55Hz, 1.5mm in
total amplitude, with about a 1-minute rate of vibration change
from 10Hz to 55Hz and back to 10Hz. Apply for a total of 6 hrs.,
2 hrs. each in 3 mutually perpendicular directions.
11
Solderability of Leads
Lead wire should be soldered with
uniform coating on the axial direction
over 3/4 of the circumferential direction.
The lead wire of a capacitor should be dipped into a ethanol
solution of 25wt% rosin and then into molten solder for 2±0.5
sec. In both cases the depth of dipping is up to about 1.5 to
2mm 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

The lead wire should be immersed into the melted solder of
350±10°C up to about 1.5 to 2mm from the main body for
3.5±0.5 sec.
