♦The Fusible resistor is applied to safety circuit in wide range of electronic sets.
Complete flame proof construction resistance range 0.12R ~ 75R ohm
Resistance tolerance : ±5%; ±10%/
There are 4 color band is in white color means wire wound fusible resistor

保險絲與電阻其材質及結構上有類似之特性,而保險絲電阻兼備二者之功能,設置於電路中可當一般電阻使用,一旦電流異常時,發揮其保險絲特性保護產品電路不致全部受損。
由於保險絲特性有二用的功能,故在設計電路時,很多工程師都會使用保險絲電阻放置於電路中,大大降低成本。本公司所生產之貼片保險絲產品,為貼片型表面封裝,適用於平面化及小型化之產品類別,功率分別由1/4W ~ 1W,價格比市面所使用的玻璃封裝和繞線保險絲電阻體積更小,成本更底,具有價格上的優勢。

using Resistor – RF10 Series
There are some similarities between resistor and fuses in material and structure, Fusing Resistor contain both function,
as being resistor in normal condition and changed into fuse while abnormal current comes in to product machine and
equipment. Since two functions performed by resistor, the cost therefore saved.
Our RF10 Fusing Resistor series are produced with precision technique, enabling precise fusing time and stabilized
aiming to reach best quality resistors.

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。
