4. POWER RATING
(1) Rated Power at 70°C :
RL0603=1/10W
RL1210=1/3W RL0805=1/8W RL2012=3/4W RL1206=1/4W
RL2512=1W
(2) Rated Voltage : The DC or AC (rms) continuous working voltage corresponding
to the rated power is determined by the following formula : V= √(P X R)
Where V= Continuous rated DC or AC (rms) working voltage (V)
P= Rated power (W) R= Resistance value (Ω
)

8. ENVIRONMENTAL CHARACTERISTICS
(1) Temperature Coefficient of Resistance (T.C.R.)
Test Method : Measure resistance at +25°C or specified room temperature as
R 1, then measure at -55°C or +125°C respectively as R 2. Determine the temperature coefficient of resistance from the following formula.
R 2－R 1 `
T.C.R.= ----------------- X 106
(PPM/°C) R 1 (t 2－t 1)
Where t 1 =+25°C or specified room temperature
atbt 2 = -55°C or +125°C test temperature
R 1=resistance at reference temperature in ohms. R 2=resistance at test temperature in ohms.
Acceptance Standard : (Refer to item 5)
(2) Thermal Shock
transform
Test Method : -55±3°C, 2 minutes and +125±2°C, 2 minutes as one cycle. After
5 cycles, the specimen shall be stabilized at room temperature for 1 hour minimum and then measure the resistance to determine △R/R(%).
Acceptance Standard : ±1.0%
(3) Low Temperature Operation
六级范文Test Method : Place the specimen in a test chamber maintained at -65 °C. After one hour stabilization at this temperature, full rated working
voltage shall be applied 45 minutes. Have15 minutes after remove the voltage, the specimen shall be removed from the chamber and stabilized at room temperature for 24 hrs. Measure the resistance to determine △R/R(%).
Acceptance Standard : ±1.0%
No mechanical damage.
