  • 电子元件基础知识

    2018.12.20

        关于其最基本的电子元件作用就是阻碍电流的流动。衡量电阻器的两个最基本的参数是阻值和功率。阻值用来表示电阻器对电流阻碍作用的大小,用欧姆表示。除基本单位外,还有千欧和兆欧。功率用来表示电阻器所能承受的最大电流,用瓦特表示,有1/16W,1/8W,1/4W,1/2W,1W,2W等多种,超过这一最大值,电阻器就会烧坏。根据电阻器的制作材料不同,有水泥电阻(制作成本低,功率大,热噪声大,阻值不够精确,工作不稳定),碳膜电阻,金属膜电阻(体积小,工作稳定,噪声小,精度高)以及金属氧化膜电阻等等。根据其阻值是否可变可分为微调电阻,可调电阻,电位器等。
