PPLICATION
There are some similarities between Resistor and Fuses in material and structure. Fusible Resistor
contain both functions, as being Resistor in normal condition and changed into fuse while abnormal
Current comes in to protect machine and equipment. Since two functions performed by one resistor,
the cost therefore saved. FRM Fusible Resistor series are produced with precision technique,
Enabling precise fusing time and stabilized, aiming to reach best Quality Resistor
FRM 保險絲晶圓電阻系列生產採用了精密技術,精確的熔斷時間和穩定的質量,旨在生產出色
的熔斷保險絲晶圓電阻。

MLH4W 電阻適用於稳压模块(PRM)稳压器

T    背光方案要求用恆定電流來驅動串連著的大功率LED列陣,一般來說,恆定電流是用來确保可預測的發光亮度和色度值。V.I 晶片非隔離預穏壓模块(PRM)穏壓器倍增電流電壓轉換模块(VTM),電壓變換器雖然主要設計用於利用適應環路穏壓方法提供穏定的電壓,但也可以通過簡單的電路修改而達至穏定的輸出電流。與傳統方法相比,使用PRMVTM提供穏定電流具有許多優點。在系統中使用VTM可以倍增負載點的電流, VTM的輸出電流正比於它輸入電流(如下公式所示Fig-1) ,其中KVTM K系數,或簡單的將其稱為壓降比。
