Crystals are widely used in a variety of electronic equipment, ranging from radios and televisions to smartphones, tablets and computer equipment. In particular, the MA-406 4.9152M-C crystal is a type of crystal often used in cutting-edge applications.

The MA-406 4.9152M-C is an oscillator crystal, specifically designed for RoHS applications and meeting certain standards. ROHS stands for "Restriction of Hazardous Substances" and is an initiative of the European Union, aimed at restricting and reducing the use of certain hazardous substances in the manufacture of electronic and electrical equipment. This particular crystal is also RoHS compliant, meaning that it does not contain any of the restricted materials. It also meets other standards such as RoHS 2, as well as IEC60950.

The design and construction of the MA-406 4.9152M-C are such that it is designed to be highly efficient, resulting in the lowest possible consumption of power. It is constructed with a 7.3mm x 5.3mm ceramic package, and has low temperature coefficient values and excellent frequency stability. Another benefit of its construction is that it eliminates the need for an external oscillator capacitor.

The working principle of the MA-406 4.9152M-C is a simple one. It consists of a quartz crystal oscillator that is designed to oscillate at a particular frequency, determined by the crystal itself. The frequency of the crystal oscillator is dependent on the dimensions of the quartz, which determines its resonant frequency, as well as the thickness of the electrodes that are connected to it. By changing the voltage applied to the electrodes, the frequency of the oscillation can be adjusted, allowing it to be tuned to the required frequency.

At the core of the crystal oscillator is a quartz crystal, made from a slab of quartz that is cut at exact angles in order to determine the resonant frequency. It is this resonant frequency that determines the frequency of oscillation. The quartz crystal is attached to two metal plates, which act as the electrodes, and through which an electrical current is passed. As the current passes through the quartz crystal, it undergoes a process called piezoelectricity, which causes it to expand and contract, producing a vibration.

This vibration produces a characteristic frequency, which is determined by the size and shape of the quartz crystal itself. As the electrical current is adjusted, the frequency of the vibration can be changed, and thus the desired frequency of the crystal can be obtained. This same principle can also be used to adjust the frequency of other types of crystals, including ceramic and fiber-optic materials.

The MA-406 4.9152M-C crystal is a highly efficient and RoHS compliant oscillator crystal that is suitable for a wide range of applications. With its small size, low power consumption and excellent frequency stability, it is the ideal choice for any cutting-edge electronic products. Its robust design and RoHS compliance make it an ideal choice for embedded devices and other next-generation products.
