HCM4920000000ABJT

The HCM4920000000ABJT crystal is a piezo-electric device that is commonly used in many electronic applications. It is used as a resonator to control the frequency of oscillators, to reduce the amount of power dissipated in electronic circuits, and to provide stability in electronic designs. Crystals of this type can usually be found in high frequency circuit designs, such as those utilized in cell phones, fire alarms, medical devices, and more.

The most attractive feature of this crystal is its size, which is about the size of a penny. Due to its ultra-small size, it can be placed within a narrow space and still provide a consistent frequency response. Its small size also reduces power consumption and makes it an ideal choice for battery powered devices.

The working principle of the HCM4920000000ABJT crystal is based on the piezoelectric effect. A piezoelectric material is one that generates a voltage or electric field when a mechanical force is applied to it. In the case of the crystal, it generates a voltage when an external electrical field is applied to it. This voltage is then used to control the frequency of a combined oscillator.

The crystal has two electrodes, which are connected to the two electrical ports of an oscillator. When an electrical field is applied to the crystal, one of the electrodes will produce an electric current, which is then amplified by the oscillator. This amplifier then produces a signal that is proportional to the applied electrical field and is used to control the frequency of the oscillator. This is known as the "crystal motor".

Crystals of this type are often used in high frequency circuits where a very precise frequency response is required. This is because the crystal can maintain a very precise frequency response over a wide range of input voltages. It also has the ability to withstand high temperatures and shock, making it well suited for applications where a consistent frequency response is essential.

The HCM4920000000ABJT crystal is a reliable and cost-effective alternative to many other crystal types. Its small size makes it an ideal choice for many applications, particularly those that require a small footprint and high frequency performance. As such, these crystals are widely used in many electronic designs.
