공식 및 규격

R(t) = R₀ [1 + A·t + B·t² + C·(t − 100)·t³]

A = 3.9083 × 10⁻³, B = −5.775 × 10⁻⁷, C = −4.183 × 10⁻¹²(0 °C 미만, 0 °C 이상에서는 0). 적용 범위는 −200~850 °C입니다. 저항에서 온도로의 변환은 0 °C 이상에서는 정확한 해로, 0 °C 미만에서는 뉴턴 반복법으로 구합니다.

허용차 등급: AA ±(0.10 + 0.0017|t|), A ±(0.15 + 0.002|t|), B ±(0.30 + 0.005|t|), C ±(0.6 + 0.01|t|) °C. 각 등급이 적용되는 온도 범위는 권선형인지 박막형인지에 따라 다릅니다.
