Crystals are solid-state objects that possess electrical, acoustic, optical, and magnetic properties and are used for a variety of purposes. As an electronically active component, crystals can be used for frequency control in radio receivers, oscillators and transmitters, filters, and so on. One such crystal is the MA-406 4.9152M-B0. This crystal is designed for use in radio and satellite communication frequency, seismic survey, and high-precision temperature measurement and control.This ROHS compliant crystal is a miniature R/C oscillator, which features a ceramic package and low-noise performance, making it a great solution for these applications. ROHS stands for Restriction of Hazardous Substances, and it is an international standard that limits the use of certain hazardous materials in electronic and electric products.When used as a frequency controlling element, the crystal oscillator works in a manner similar to a phase locked loop. First, an oscillating voltage or current is applied to a piezoelectric material, such as a quartz crystal, to create an oscillation. This oscillation is then feedback to an amplifier and other components to stabilize the oscillation at the frequency determined by the crystal. As the oscillation frequency is determined by the properties of the piezoelectric material, and the oscillator circuit is designed to maintain the same frequency, the crystal oscillator is said to be “frequency locked” to the oscillator circuit.In addition to frequency control, crystals can be used as a power source in certain cases. When used to power other electronic components, they can supply an initial start-up surge of energy and then sustain a steady and reliable level of output. This type of application is commonly seen in watch and clock crystals, as well as in some automotive applications, where intermittently powered devices are used in order to conserve energy.Overall, the MA-406 4.9152M-B0 crystal is a great solution for radio and satellite telecommunications, and any other application which requires precise frequency control, power, or environmental compliance. By utilizing the tightly controlled frequency of this crystal’s oscillation, and its ROHS compliant construction, it is possible to achieve superior performance and environmental awareness.
