Crystals are one of the most important components in many electronic devices. They are what make electronic components oscillate at precise frequencies. FA-238 25.0000MB-K is one of the most popular oscillator crystals used both on consumer level and in industrial applications.

Product Description

The FA-238 25.0000MB-K is a low-cost, surface-mount oscillator crystal with a frequency tolerance of ±50 parts per million (ppm) and an aging rate of ±2 ppm per year. It has an operating temperature range of –20°C to +70°C and a storage temperature of –54°C to +124°C. It features an 8 pad MHS 0.8×1.0 mm package, making it ideal for use in small spaces. In comparison to other oscillator crystals, it has a lower cost and improved package size.

Application Field

The FA-238 25.0000MB-K is widely used in consumer electronics, such as cell phones, PDAs, digital cameras, MP3 players, and other portable devices. It is also found in computer peripherals such as modems, digital TV tuners, and satellite receivers. It is also used in automotive applications, such as engine control systems and navigations systems.

In industrial applications, the FA-238 25.0000MB-K is used in a wide range of products, such as frequency voltage controllers and power supplies for inverters, switching power supplies, and SMPS circuits. It can also be found in vibration sensors, debit and credit card readers, and medical instruments.

Working Principle

Oscillator crystals work on the principle of piezoelectricity, which states that when certain materials are compressed or stretched, they will generate an electric charge. The FA-238 25.0000MB-K utilizes this principle to generate a stable frequency signal. When voltage is applied to the crystal, it creates a physical oscillation, which in turn generates a high frequency oscillation. This oscillation is then amplified and stabilized by the surrounding circuitry. This allows the oscillator crystal to generate a very precise, stable frequency signal.

The temperature variation of the oscillator can be compensated for using a temperature compensation circuit. This circuit is designed to maintain the specified oscillator frequency tolerance over the specified temperature range, ensuring that the frequency does not drift with temperature changes.

The FA-238 25.0000MB-K is an excellent choice for low-cost, high-precision oscillator applications. It offers a low-cost solution with good frequency stability, and its small form factor makes it ideal for use in space-constrained environments.
