山东德庆电阻器RZe54-280S-6/5电阻温度系数小呈直线变化

电阻器的选型

   1.在高增益放大电路中.应选用噪声电动势小的电阻器，如金属膜也阻器、碳膜电阻器和线绕电阻器。

   2.针对电路的工作频率选用不同类堪的电阻器。线绕电阻器的分布参数较大，即使采用无感绕制的线绕电阻器，其分布参数也比非线绕电阻器大得多，因而线绕电阻不适合在高频电路中工作。在低于50kHz 的电路中，由于电阻器的分布参数对电路工作影响不大，可选用线绕电阻器。

3.在高频电路中的电阻器，要求其分布参数越小越好。所以，在高达数百兆赫的高频电路中应选用碳膜电阻器、金属膜电阻器和金属氧化膜电阻器。在超高频电路中，应选用超高频碳膜电阻器。
