特點：
1 耐熱性好、溫度系數小、噪聲低、負荷功率大 Good heat-durability,low temperature coefficient,low noise,high overload power。
2 使用環(huán)境溫度 Operating ambient temperature:-55~+125ºC。
3 表面涂不燃性面漆，1/4W~6W用色環(huán)標識阻值，涂漆著色為灰白色，色環(huán)后增加綠色環(huán)表示無感；7W以上用印字標識阻值，涂漆顏色為綠色 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 阻值誤差 Resistance tolerance:1% 2% 5% 10%
