Test Method
Resistor was dipped into solvent for 5 ± 0.5 minutes
Measured resistance (R 0 ohm) at room temperature (t oC) then
measured again at 100oC higher than room temperature
6
Applied DC voltage 2.5 times the rated voltage for 5 seconds ON,
45 seconds OFF. Repeated cycle 10 times. Maximum Overload
voltage is not more than 2 x Max Working Voltage
Resistor was clamped in the through of a 90oC metallic V-block and
was tested at provided AC potential voltage for 1 minute.
Test voltage: max overload voltage. Test voltage: 500V (AC)
Applied 1.5mm amplitude vibration to two directions, perpendicular to
each other, for 6 hours each. Total 12 hours.
Vibrating frequency is 10HZ - 2000HZ - 10HZ cycle in 20 minutes.
Repeat cycle.
Resistor was clamped in the through of a 90oC metallic V-block at DC
100V for 1 minute
Tensile test: The body of the part is fixed. The tensile force was
applied gradually up to 10N. Twist test: Terminal lead was rotated
360o of the original axis of the bent terminal, alternating direction for 3
rotations.
Resistance to wave soldering condition:
Temperature/Time-Profile in accordance to the CECC00802.
Max Temperature/Time: 260oC, 10 seconds
Solderability
More than 95% of the lead surface was covered by Dipped the lead into a solder bath (temperature 245oC ± 5oC) up to 4
new solder after the leads were dipped in the solder ± 0.8mm from the resistor body and held for 5 ± 0.5 seconds.

Test: -55oC for 30 min., 25oC for 30 sec., 155oC for 30 min. 25oC for
30 sec. Resistance changed after continuous 5 cycles.
Temperature 40oC ± 2oC, relative humidity 90~95%, inside bath for
1.5 hour and shut voltage 0.5 hour. Repeated cycle for 1,000 hours.
Room temperature for 1 hour after test, then measured
In constant temperature chamber 70oC ± 2oC, applied rated DC
voltage for 1.5 hour and shut voltage for 0.5 hour.
Cycle repeated for 1,000 hours.
Resistor was put into a bath at fixed temp of -55oC ± 3oC for 2 hours.
After measured, left at room temp for 1 hour,
then measured again.
Resistor was put into a bath at fixed temp of 155oC ± 3oC for 16
hours. After measured, left at room temp for 1 hour,
then measured again.
In accordance with IEC60065.14.1, 50 discharges from a 1nF
capacitor charged to Vmax; Figure 2. 12 discharges/minute
