    直插电阻

    直插电阻是什么?

    直插电阻是一种固定电阻,由一般用途的金属膜或用于需要高耐受性的设备的碳膜构成。它们有长而柔韧的引线,可以(自动或手动)插入印刷电路板的孔中。

    直插电阻的种类

    • 碳质电阻器:成本低阻值范围宽,但其阻值误差和噪声电压比较大,稳定性差,较少使用。
    • 碳膜电阻器:精度和稳定性一般,但其高频特性较好,受电压和频率影响和噪声电动势较小,脉冲负荷稳定,阻值范围较宽。因生产成本低,价格价廉,故在消费类电子产品中仍然应用广泛。
    • 金属膜电阻器:耐热性、噪声电势、温度系数、电压系数等电性能比碳膜电阻器优良,与碳膜电阻器相比,金属膜电阻器体积小、噪声低、稳定性好,但成本稍高。金属膜电阻器作为精密和高稳定性的电阻器获得广泛应用,通用于各种电子设备中。
    • 金属氧化膜电阻器:电阻率较低,小功率电阻器的阻值不超过100KΩ,因此应用范围受到限制,但可用作补充金属膜电阻器的低阻部分。
    • 绕线电阻器:体积大、阻值较低,大多在100KΩ以下,通常在大功率电路中作降压或负载等用。

    直插电阻的应用

    直插电阻适合不需要焊接的大型电路板和原型制作项目,通常用于汽车、电信和医疗设备行业。
