3.0 Power Rating:
Resistors shall have a power rating based on continuous load operation at an ambient temperature from -55℃ to 70℃.
For temperature in excess of 70℃, the load shall be derate as shown in figure 1.
3.1 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:
Where: RCWV= Rated dc or RMS ac continuous working voltage at commercial-line frequency and waveform (VOLT.)
P=Power Rating (WATT.)
R=Nominal Resistance (OHM)
In no case shall the rated dc or RMS ac continuous working voltage be greater than the applicable maximum value.
The overload voltage is 2.5 times RCWV.
4.0 Structure:
1. High purity alumina substrate
2. Protective covering
3. Resistive covering
4. Termination (inner) Ni/Cr
5. Termination (between ) Cu
6. Termination (between) Ni
7. Termination (outer) Sn
5.0 Marking:
(1) For CS02 size: Due to the very small size of the resistor’s body, there is no marking on the body.
CS02
(2) For CS03 size: Below 100mΩ(do not contain), show as following:
056 → 0.056Ω
(3) For CS03 size: Above (contain) 100mΩ product: 3 digits, the first digit is “R”, which as decimal point, the 2
nd
digits are significant.
R10 → 100mΩ

(4) ±1%, ±5% Tolerance: product below 1Ω show as following, the first digit is “R”, which as decimal point.
R050 → 50mΩ
R100 → 100mΩ
(5) ±1%, ±5% Tolerance: product of 1Ω show as following, the first digit is “1”, read alphabet “R” as decimal point.
