Crystals are components commonly used in electronic circuits and one of their important products is the MP042A-E crystal. This is a vacuum sealed AT-cut crystal, making it a reliable source of precise frequency. The device is usually used in oscillators, circuits used to generate signals of a precise frequency.

The MP042A-E crystal is typically used in RF applications and has a wide range of applications. Examples include radio receivers and transmitters, oscilloscope systems and other precision measurement circuits. It is also used in global navigation satellite systems as well as frequency control circuits.

The MP042A-E crystal has a very accurate frequency, very low phase noise and low ESR that makes it ideal for high-precision applications. The crystal also has a wide frequency range, which is typically between 7 and 48 MHz.

The MP042A-E crystal has a unique design that ensures it has low noise and a wide frequency range. The crystal comprises two MT-cut quartz plates with a sensing electrode between them. These plates are held in place by a hermetically sealed inner ceramic package, which contains a special low-friction element. This special element eliminates unnecessary vibration and mechanical stress thereby increasing the accuracy of the frequency.

The crystal also has a built-in temperature compensation device that automatically adjusts the frequency output of the device to counter any changes in the temperature. This ensures that the device always has an accurate frequency output even if the temperature in the environment changes.

In operation, an alternating current is fed into the sensing electrode between the two quartz plates. This creates an oscillating voltage. At resonance, the frequency of the oscillating voltage matches the natural frequency of the quartz plates. The frequency output is then adjusted by the temperature compensation unit to ensure accuracy.

The MP042A-E crystal is a reliable and precise source of frequency and is widely used in RF communication applications. Its low-noise and wide frequency range makes it ideal for precision measurement circuits. The built-in temperature compensation device also ensures accuracy even when the temperature in the environment changes.
