Resistive Product Solutions
At 70 ± 2ºC, apply rated DC voltage 1.5 ON, 0.5 hour OFF for 1000 hours and
leave in room temperature for one hour after test.
Change of resistance
≤ ± (5%+0.05Ω)
The resistor shall be subjected to 5 continuous cycle,
each as shown in the table below:
Change of resistance
≤ ± (1%+0.05Ω)
Rapid Change of
Temperature
Apply 1.5mm amplitude vibration to three directions perpendicular to each
other 2 hours each, total 6 hours. Vibrating frequency is 10Hz-55Hz-10Hz
cycle in 1 minute sweeping and repeat cycle
Change of resistance
≤ ± (1%+0.05Ω)
Change of resistance
≤ ± (5%+0.05Ω)
In the chamber having temperature of 40 ± 2ºC and relative humidity of
93 ± 3%, apply one percent of the rated power, 1.5 hour ON, 0.5 hour OFF
for 1000 hours and leave in room temperature for one hour after test.
Robustness of
Terminations
Dip the lead into a solder bath having a temperature of 260ºC ± 5ºC up
to 1.5 ± 0.5 mm from the body of the resistors and hold it for 10 ± 0.5 seconds
and leave in room temperature for one hour after test.
Change of resistance
≤ ± (1%+0.05Ω)
Resistance to
Soldering Heat
More than 95% of the
surface of the lead will be
covered by new solder
Dip the lead into a solder bath having a temperature of 245ºC ± 5ºC up
to 1.5 ± 0.5 mm from the body of the resistors and hold it for 5 ± 0.5 seconds.
The body of the resistor is fixed, a static load is added in the direction of
drawing out of the terminal, and it maintains it for 10 ± 1 seconds.
Component body will be fixed so that terminals are perpendicular to the floor.
A static load specified below shall be applied to the terminal acting in a
direction away from the body. The body of piezoelectric oscillator will be
inclined through an angle of 90ºC and then retuned to its initial position
in 2 or 3 seconds
Change of resistance
≤ ± (0.5%+0.05Ω)
Soak in a Isopropyl alcohol for 5 minutes. After drying up for 5 minutes, the
stress of 5N is added with the absorbent cotton. Five round trips at the rate of
one round trip a second.
There will be no damage
on the insulating surface
Apply 2.5 times rated voltage or max overload voltage whichever is lower for
5 seconds and leave in room temperature for one hour after test.
Temperature Coefficient
of Resistance
Lay the resistor on the 90º angle metal V block and
apply rated AC voltage for one minute
Lay the resistor on the 90º angle metal V block and apply 100Vdc between
V block and lead wire for a minute. The insulation resistance will be measured
while applying the voltage.
Measure resistance (R
0
) at room temperature (t), after that, measure again
the resistance (R) at 100ºC higher than room temperature
