Micro SD卡座连接器已成为电子产品不可或缺的电子元器件，Micro SD卡座连接器常用于手机、电脑、平板、汽车、安防设备、智能家电等电子设备中。下面摩凯电子为大家分享一些Micro SD卡座连接器的电气性能和机械性能指标。

1. 特性阻抗

与其他微波器件一样，特性阻抗是一项非常重要的指标，它直接影响工作频率和插入损耗。常见的Micro SD连接器特性阻抗为50Ω和75Ω。

2. 低接触电阻

Micro SD卡座的接触电阻是指Micro SD储存卡与Micro SD卡座接触端子的接触阻值。显然这个值越小越好，通常以mΩ为单位，一般Micro SD卡座的低接触阻值小于100mΩ。

3. 绝缘电阻

绝缘电阻指绝缘材料的电阻值,它取决Micro SD卡座所选用的绝缘材料。绝缘电阻一般大于1000mΩ，绝缘电阻过小会产生漏电流现象。

4. 耐久性（插拔寿命）

当Micro SD卡完全插入卡座后再完全拔出这一循环称其为一次插拔。Micro SD卡座的插拔寿命为5000次。
