Cement Resistor - SQT Type

按圖放大 水泥電阻

PDF File  Data Spec Cement Resistor - SQT Type

Cement FEATURE

  • Exceptionally small and sturdy, mechanically safe.  
  • Excellent electrical characteristic  
  • Tolerance of ±5% and ±10% are standard.  
  • Non-inductive type are available on request.  
  • Heat and flame resistance   
  • The materials used and the construction techniques ensure excellent   flame resistance, arc resistance and moisture resistance as well as self-extinguishing capabilities, They will withstand the most rigorous loading test.
  • As resistors in radio and television receiver, The hazardous conditions of  smoking and reheat can be completely prevented by the proper choice of power resistors.
  • For high resistance value, The winding core will be replaced by metal oxide film core (RS Type)
  • Applicable specifications: EIA RS-344 and EIA RC-649

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。
