Resistor INTRODUCTION
The FCR series flame-proof Carbon Film Resistors are manufactured by Coating a homogeneous film of pure carbon on
high grade ceramic rods, resistance less than 10 have an electro less deposited nickel film, and are coated with layers
of gray color flame-proof lacquer. These resistors meet overload tests in accordance with UL specification  without
producing a fire hazard.

TVS 二極體是一種十分有效的保護元件
 產品應用 TVS 二極體是一種十分有效的保護元件
TVS 與其它元件相較有其獨特的優勢,但在應用時應當針對不同的保護對象來選用元件,因為不同的連接埠可能受到的靜電衝擊有
所不同,不同元件要求的保護程度也有不同。產品由於頻繁與人體接觸極易受到靜電放電(ESD)的衝擊,如果沒有選擇合適的保護元
件,可能會造成機件性能不穩定,或者損壞,更壞的情況是查不出確切的原因 。傳統的保護方法已己不能满足現今產品質檢的要求,
不當的選擇使用保護器件,有的甚至還會造成對設備性能的干擾。
