General Description
The miniature CX-1HG-SM AT-cut crystals in leadless ceramic
packages have been designed for surface-mounting on printed
circuit boards or hybrid circuits. These crystals are designed for
applications requiring exceptional shock and vibration survival.





Surface-mount - infrared, vapour phase,
wave solder or epoxy mount techniques
Low profile, hermetically sealed package
Available with glass or ceramic lid
High shock and vibration resistance
Custom designs available
Full military environmental testing available

I came into contact with MSP430 in 2003!
The most impressive thing about 430 is its low power consumption! In addition, it is a 16-bit microcontroller. Coupled with the power of IAR, developing 430 becomes a breeze. It has a wide range of pe...

How do you calculate the current in this circuit?
Hello everyone:As shown in the figure, the voltage at point A is 5.8 Vp-p, and the voltage at point B is 6 Vp-p. If the capacitive reactance of C1 and C2 is ignored,how can I calculate the effective v...

C2000 SPI sends 8-bit data, some experience
The C2000 SPI sends 8-bit data, but the manual does not contain any specific instructions on how to do it. When using F28035 to drive the serial 12864, I used SPI. After a long time of debugging, I co...
