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。

Fusing 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.
應用說明:
保險絲電阻與電阻器在材質及構造上本身就有類似之處,而保險絲電阻器具有兩者之特性功能,在正常使用情況下可當作一般電阻,
一旦電流有異常時就可發揮其保險絲的作用來保護電器等產品設備。
高端產品及其它需要UL安全認證之家電產品,採購使用保險絲零部件時,也必需具備有UL認證的保絲電阻廠家才能取得相關的認證。
本司所經銷之RF 保險絲電阻也已具備了這一認證條件。查詢更多資料請向本司業務部接洽。

感測電阻在電路中之應用

Current Sension Chip Resistor  按此還有更多 感測電阻在電路中之應用

在電流路徑中以串聯的方式插入一個低電阻值的感測電阻,將會形成一個較小的壓降,該壓降可被放大而成為一個與電流成正比的輸出訊號。然而,根據實際應用環境與感測電阻的位置,這一技術可能對感測放大器帶來各種挑戰。例如,將感測電阻放在負載與電路接地之間,那麼所形成的壓降可採用簡單的運算放大器(OP)進行放大。這種方法被稱為低側電流感測,與其相對應的方法為高側感測,即感測電阻位於供電電源和負載之間。 

Figure Circuit CS

電流的感測一般採用兩種基本方案。一種是測量電流流過的導體周圍磁場,另一種是在電流路徑中插入一個小型電阻,然後測量電阻上的壓降。第一種方法並不會引起干擾或插入損耗,但成本相對較為昂貴,而且容易產生非線性效應與溫度係數誤差。因此磁場感測技術通常只局限於一些能夠承擔無插入損耗的高成本應用。
