Vectron International designs and manufactures HC49 series resistance weld crystals for a wide variety of commercial and high
reliabilty applications.
Our proven processes yield excellent aging and low perturbations.
We have tight controls over series
resistance, motional capacitance, temperature characteristics and other parameters critical to your application. We primarily build
to customer specifications but we’ve optimized designs on all frequencies that are commonly used in telecommunications. Tighter
performance requirements than those shown above may be available.
Please feel free to contact us with your questions. We are here to assist you with selecting the best performing and most cost ef-
fective crystal for your application.
