Mayloon Products Power Resistor ML series resistors satisfy demanding applications for accurate and stable power resistors housed in the convenient TO-220 case. The resistance element is
Isolated from the mounting tab by an alumina ceramic layer, providing very low ther- mal resistance and ensuring high insulation resistance between terminals and tab.
The non-inductive design makes these products especially useful in high frequency and high speed pulse applications.

    電阻如何能表現相對較小的電阻值變化

      產品應用      電阻如何能表現相對較小的電阻值變化

    黃金鋁殼功率型繞線電阻器

    電阻在電路中因產生的熱能會使電阻的功率下降,消耗的能量使電阻不能得到應有的效率,電阻功率也會因溫度的升高而降低,如果沒有好的散熱體,超出其額定的最高工作電壓就會燒燬,黃金鋁殼功率型繞線電阻針對這一問題而生產出來的,其工作溫度範圍由-55~275 (一般電阻由-55~175),而且穏定,使用了鋁合金外殼設計溝槽增加散熱效能,適合使用在比較惡劣下的工作環境。在一個理想的電阻器裏,電阻值不會隨電壓或電流而改變,亦不會因電流的突然變動而改變。現今的內部結構設計使電阻器在極端的電壓或電流及在環境溫度惡劣情況下能表現相對較小的電阻值變化了。
