4. Marking

(1) For 01005、0201 and 0402 size. Due to the very

01005、0201、0402 small size of the resistor’s

body, there is no marking on the body.

(2)Normally, the making of 0 0603, 0 0805,

0 1206, 0 1210, 0 1812, 0 2010,

0 2512 resistors as following

(3) ±2%,5%Tolerance:The first two digits are

significant figures of resistance and the third

denotes number of zeros following

(4) ±0.5%、1% Tolerance: 4 digits, first three

digits are significant; forth digit is number of

zeros. Letter r is decimal point.

(5) More than 0805 specifications (including) 4 digits,

Product below 1Ω, show as following, the first digit

Is “R” which as decimal point.

9. Derating Curve

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 derated as shown in figure 1

Figure 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:

RCWV =

P



R

Where: RCWV 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 or Max. Overload voltage whichever is less
