445A32L24M00000 application field and working principle

Crystals have numerous application fields, ranging from technology and medical engineering to aviation, chemistry and optics. The model 445A32L24M00000 has widely been used in the medical device industry, in particular it is often employed as an oscillator in pacemakers, as well as ophthalmic instruments.

Crystals are part of piezoelectric technology. Piezoelectricity occurs when certain materials, such as crystals, are exposed to pressure, or mechanical stress. This is referred to as the application of strain energy. The response of the material is the development of electrical energy, in the form of a voltage, which can be measured and then used. This change in electrical energy is directly related to the force, or strain, applied to the crystal.

The 445A32L24M00000 is comprised of a single quartz element that has dimensions of 0.953 x 0.953 x 0.5 mm, and utilizes a standard, off-the-shelf crystal holder. This crystal holder protects the quartz element and ensures that electrical connection to the quartz element, while preventing the resonance frequency from being affected by any external environmental conditions.

Crystals are natural, piezoelectric semiconductors, that can be tuned or cut to resonate at a specific frequency. When a DC voltage is applied, the crystal vibrates, due to its piezoelectric effect. This produces an alternating current that has the same frequency as the vibration of the crystal. This oscillating current is what is used in pacemakers and ophthalmic devices.

This crystal is designed for high stability and performance in applications requiring a narrow bandwidth, high linearity, and low offset frequency. It is designed for a frequency of 32.768 kHz with a variation of + 10 ppm in an ambient temperature range of - 10 to + 60 °C. It features a typical motional capacitance of 8PF and a nominal series resistance of 15 ohms.

The 445A32L24M00000 is capable of producing a frequency of 32.768 kHz at a temperature range of -10°C to +60°C, with a variation of 10ppm. This makes it a reliable and stable option for medical device applications. Plus, due to its low cost and single quartz element, it is a great choice for mass production of high-volume medical equipment such as pacemakers and ophthalmic instruments.
