NTC (Negative Temperature Coefficient) is the negative Percent resistance change per degree C. To determine

The resistance tolerance of a precision thermistor at any times the NTC.

As an example, a Curve A thermistor with a temperature Tolerance of ±1 over the temperature range 0° to 70 would have the following resistance tolerance: 0=±5.1%;25=±4.4%;70=±3.4% RT/R25

Ratio is the resistance at temperature divided by the resistance at 25. To determine the resistance at other temperature points, multiply the coefficient by the R25 value.

Ratio TOL(Tolerance) is the resistance tolerance at a temperature point due to slope variance from the nominal R-T Curve. This tolerance applies to thermistors point- Matched to a single temperature point.

The ratio tolerance is added to the percent resistance tolerance at the point- Matched temperature.

NTC(負溫度係數)是負百分比電阻變化每度℃.要確定一個精確的電阻誤差的熱敏電阻的溫度系數。例如一個曲線 A熱敏電阻與溫度誤差 ± 1以上的溫度範圍 0 °70,有以下的電阻誤差值:0= ± 5.1; 25 = ± 4.4; 70 = ± 3.4 , RT/R25 比率是電阻溫度除以電阻在25。為了確定電阻值在其它位置的溫度點,乘以係數由R25的值。比率Tol(誤差)是電阻誤差的溫度點,其溫度變化RT曲線。適用於熱敏電阻誤差點的一個溫度點。 (內容說明謹供參考)
