Crystals

Crystals are solid materials composed of atoms, molecules, or ions arranged in a periodic and repeating order. Their unique structure gives crystals special physical, chemical and electrical properties. Crystals are used in a diversity of applications from electronic communication to leisure activities.

445I25A27M00000 application field and working principle

A 445I25A27M00000 crystal is a type of quartz crystal used in frequency control and timing applications. It is a small, medium-frequency crystal with a frequency range of 10 KHz to 30 MHz and a frequency stability of ±50 ppm. It is used in a wide variety of electronics, such as clocks and watches, frequency synthesizers, RF communication systems, tilt-sensors and accelerometers.

A quartz crystal works by using the piezoelectric effect. In a piezoelectric crystal, when a mechanical force is applied to the crystal, a proportional electric polarization appears in the crystal. If a voltage is applied to the crystal, mechanical deformation proportional to the electric field will appear. This deformation causes the crystal to vibrate with a frequency that can be accurately maintained and controlled.

The 445I25A27M00000 crystal is made of a combination of quartz and ceramics. The quartz provides good chemical stability and the ceramics provide increased robustness and mechanical stability under chemical and thermal stress. This combination gives this crystal excellent temperature characteristics and improved performance over standard quartz crystals.

The 445I25A27M00000 crystal is used in a wide variety of electronics, from timing and frequency control applications to tilt-sensors and accelerometers. It is also used in communications systems such as GSM, CDMA and WCDMA, and in many consumer electronics applications such as clocks and watches. It is an efficient and reliable way to maintain and control a precise frequency in many applications.
