特点：

1 耐热性好、温度系数小、噪声低、负荷功率大 Good heat-durability,low temperature coefficient,low noise,high overload power。

2 使用环境温度 Operating ambient temperature:-55~+125ºC。

3 表面涂不燃性面漆，1/4W~6W用色环标识阻值，涂漆着色为灰白色，色环后增加绿色环表示无感；7W以上用印字标识阻值，涂漆颜色为绿色 surface is nonflammable,the1/4W~6W coating is gray white and indicate the resistance value by color ring,indicate a green ring at the behind of the precision color ring;the 7W or over will indicate the resistance value by lettering and coating is green 。

4 阻值误差 Resistance tolerance:1% 2% 5% 10%
