WIREWOUND RESISTORS FLAME-PROOF
COATING
不燃性塗裝繞線電阻
INTRODUCTION
KNP type is to wind the resistance wire on a
alkaliless ceramic basic coated
with non-corrosive and high insulating heat
proof material.
把電阻線繞在無碱性耐熱瓷件上，外面加上耐熱、耐濕、
無腐蝕之材料保護而成，並於電阻體外面塗裝矽利康
(silicon)樹脂或不燃性塗料而成，其阻值誤差少。
FEATURES
 Super heat dissipation.
 Small linear temperature coefficient.
 Instant overload capability.
 Low noise figure and without annual
shift on resistance value.
特性
 耐熱性優；電阻溫度係數小，呈直線變化。
 耐短時間超負載；低雜音，阻值經年無變化。
 不燃性，重量輕，價格比琺瑯電阻便宜。
 不似琺瑯電阻高溫燒成，此種電阻線持久而不損壞。
