Description
Vectron International has introduced a series of low profile
surface mount, Temperature Compensated Crystal
Oscillators (TCXO’s) available in frequencies from 1 to 77.76
MHz.
The TC-350 series surface mount TCXO can be mounted
using the standard convection reflow process. Current drain
to less than 5 mA is available upon request. Aging <5 ppm
for ten years.
