无源晶振就是石英晶体谐振器的别称，英文名（crystal），无源晶体没有电压的问题，信号电平是可变的，主要用在各种电子线路中起产生频率的作用。是有2个引脚的无极性元件，需要借助于时钟电路才能产生振荡信号，自身无法振荡起来，分为直插式与贴片式。

用于智能家居应用晶振Q22FA23V0010600,3225mm贴片晶振
石英晶体谐振器是一种生活中随处可见的电子器件，诞生于20世纪20年代初，因具有较高的品质因数及良好的频率稳定性，被广泛应用于航天、通信、军事等工业领域。顾名思义，制造石英晶体谐振器的原材料就是石英，一种非常重要的压电材料。其主要特征是其原子或分子有规律排列，反映在宏观上是外形的对称性，在电场的作用下，晶体内部产生应力而形变，从而产生机械振动，获得特定的频率。
