4. Marking
(1) For TC02 size. Due to the very TC02 small size
of the resistor’s body, there is no marking on the
body.
(2) ±0.1%、0.25%、±0.5%、±1% Tolerance:
4 codes.
1st~3rd codes are the significant figures of resistance value,
and the rest code is the power of ten.

8. Derating Curve
Power rating will change based on continuous load at ambient temperature from -55 to 155℃.
It is constant between -55 to 70℃, and derate to zero when temperature rise from 70 to 155℃.
Voltage rating:
Resistors shall have a rated direct-current (DC) continuous working voltage or an approximate sine-wave
root-mean-square (RMS) alternating-current (AC) continuous working voltage at commercial-line
frequency and waveform corresponding to the power rating, as determined from the following formula:
RCWV √
R
Remark: RCWV: Rating Continuous Working Voltage (Volt.) P: power rating (Watt)
R: nominal resistance (Ω)
In no case, the rated DC or RMS AC continuous working voltage must be greater than the applicable maximum value.
The overload voltage is 2.5 times RCWV or Max. Overload voltage whichever is lower.
