Products Description
Quartz
Quartz crystal is a kind of piezoelectric crystal. The piezoelectric effect of quartz crystal is used to realize frequency control, stability or selection. The electronic components made include quartz crystal resonators, quartz crystal oscillators and quartz crystal filters. Mainly used in communications, home appliances, automobiles and other various industrial and consumer electronics products.
Typical application :
surface wave substrate
optical window
Carrier Wafer or Bulk Wave Chip
Also used to make commercial and military grade crystals
filter
OCXO
TCXO
