Suntan is a Hong Kong based manufacturer of Quartz Crystal and Crystal Oscillator. Including crystal oscillators and quartz crystals in a variety of package types. Quartz is a piezoelectric material that moves when placed in an electric field. A quartz crystal is a vibrating piece of quartz. Quartz crystals are available in a myriad of shapes and sizes, and can range widely in performance specifications. Please refer to below product list of Quartz Crystal and Crystal Oscillator.
Quartz crystals are widely used in today's electronics circuits as high quality tuned circuits or resonators. Such as like GPS,Mobile phones, consumer products,Computers,oil-driling and other high-reliable product applications.Despite their high performance quartz crystals are cheap to produce and they find many uses in applications from oscillator clock circuits in microprocessor boards, the timing element in digital watches as well as their more traditional applications in radio frequency applications where they may be used as the resonators in highly stable quartz crystal oscillators of high performance crystal filters.
As the name implies quartz crystal resonators are made from quartz, a naturally occurring form of silicon, although most of that used for electronics applications is manufactured synthetically these days. The components rely on the remarkable properties of quartz for their operation. When placed into an electronic circuit a crystal acts as a tuned circuit. However it has an exceptionally high Q. Ordinary LC tuned circuits may exhibit values of a few hundred if carefully designed and constructed, but quartz crystals exhibit values of up to 100 000. Apart from their Q, crystals also have a number of other advantages. Their stability is remarkably good with respect to temperature and time. In fact most crystals will have these figures specified and they might typically be 5 ppm (parts per million) per year for the ageing and 30 ppm over a temperature range of 0 to 60 degrees Celsius.
Quartz crystal resonators are widely used within the electronics industry. They can be used in quartz crystal oscillators and crystal filters where they provide exceptionally high levels of performance. In addition to this, low cost elements with lower tolerance specifications are widely used in crystal oscillators for microprocessor board clocks where they are used as cheap resonator elements. Whatever its use a quartz crystal resonator provides an exceptionally high level of performance for the cost of its production.
Quartz crystals used in radio and electronics circuits are precision electronic components and when buying them it is necessary to be able to specify them precisely. There are normally several elements to a crystal specification, many of which are specific to quartz crystals and not widely used elsewhere in radio applications. Also there are a number of elements to a crystal specification that may be set down by the manufacturer for a given range of crystals and when ordering a component it is necessary to be aware of them.
