这几个元器件封装,你肯定搞不清!
这几个元器件封装,你肯定搞不清!
DO-214 is a standard that specifies a group of semiconductor packages for surface mounted diodes.
The standard includes multiple variants such asDO-214AA (SMB), DO-214AB (SMC), and DO-214AC (SMA).DO-214AC (SMA) is the smallest,DO-214AB (SMC) is the largest.DO-214AC (SMA) < DO-214AA (SMB) < DO-214AB (SMC)从以上的图片看来,这三种封装看上去差不多,没什么区别,但从实物体积上来分,可以看出:
