MC-306 31.9990KA-G3:ROHS
MC-306 31.9990KA-G3: ROHS is a type of crystal commonly used in electronic circuits which have excellent stability of frequency, low aging rate and good reliability. This type of crystal is used for modulating and demodulating signals in radio receivers, clocks and transmitters, as well as for controlling frequency in quartz oscillators, particularly in amplifiers, radio receivers, computers and timers.
It is composed of a quartz crystal inside a sealed casing, which is usually made of metal or ceramic. The crystal itself is formed by a thin plate of quartz cut in the shape of a prism, which is then carefully trimmed and mounted between two electrodes. The two electrodes are connected to external circuitry through two pins. Inside the crystal is an oscillator, which generates a frequency that is determined by the size of the crystal and can range from several kilohertz to tens of megahertz.
The crystal oscillator works by being subjected to an alternating electric field known as an LC network. When the voltage is applied, an electrical charge passes through the crystal, oscillating between positive and negative. This oscillation is converted into a frequency that is detected by external circuitry attached to the crystal. The oscillation is also known to modulate the output signal, thus allowing for signal modulation and demodulation in receivers, transmitters and computers.
The MC-306 31.9990KA-G3: ROHS crystal is used mainly in the fields of clocks, timers, signal processing and radio transmitters. In clocks and timers, the crystal is used to provide accurate timing signals and to regulate the internal frequency in quartz oscillators. In signal processing and radio transmitters, the crystal is used to provide precise control over signal modulation and demodulation and to lock signals at a constant frequency.
The MC-306 31.9990KA-G3: ROHS crystal provides much greater stability, accuracy and reliability than analogue alternatives and has been essential in advancing the quality of electronics. Due to its reliability and accuracy, the MC-306 31.9990KA-G3: ROHS crystal is increasingly becoming a preferred choice for manufacturers and engineers alike.
