Crystals are materials with a regular, repeating lattice structure, which is highly established due to the attractive forces of their atoms being strongly held in position. These components oscillate at a specific vibrating frequency, known as resonant frequency, when they are excited by an alternating current. This is what gives crystals their exceptional electrical properties, making them indispensible components of electrical and electronic equipment.

The MP018A-E series follows a standard SMD (Surface Mounted Device) package, making them ideal for use in a variety of applications, such as mobile phones, PDAs, and a range of other high frequency applications. This range of crystals adopts an AT-cut oven-controlled crystal oscillator technology, which offers higher time stability and frequency accuracy than traditionally used crystals.

The MP018A-E series is mainly utilized to control frequency and timing intervals in electronic circuits. It is a highly reliable quartz crystal resonator, with excellent anti-interference performance, suitable for a wide range of environmentally hostile industrial, telecommunication and medical application environment. Moreover, the high-precision frequency is maintained by the AT-cut technology and uses a voltage controlled crystal oscillator (VCXO), allowing for better temperature stability for the device.

The working principle of the MP018A-E series is based on the control of frequency given by an external voltage, as a way of adjusting timing parameters within an oscillator circuit. The frequency is determined by the product of an external static voltage, applied to the crystal, and the electrical capacitance of the crystal itself. To deliver accuracy, the voltage control crystal oscillator (VCXO) is constructed from a quartz crystal, mounted in a metal package with a sealed cavity and electrodes making up the crystal.

In the MP018A-E series, not only is the crystal selected for its frequency of oscillation, but also for its temperature stability, which is particularly important within mobile devices. Therefore, the frequency of the MP018A-E series is precisely tuned and its crystal is oven-controlled within a temperature range of 25 ± 5°C; this helps to ensure a maximum frequency deviation of ±30 ppm over the operating temperature range.

In conclusion, the MP018A-E series of crystals hold many advantages over other standard crystals, providing greater accuracy due to their AT-cut oven-controlled oscillator technology and higher stability due to the voltage control crystal (VCXO) feature. The particular combination of these features, along with the standard SMD package, makes the MP018A-E series the ideal choice for use in a variety of applications, where accuracy and stability are of prime importance.
