It operates at a frequency of 32768 Hz (32.768 kHz) and has a total tolerance of ±30 ppm. The 425F11A027M0000 is a hermetically sealed crystal and is protected against moisture and dust, making it well-suited for use in extreme temperature and high-humidity environments.

The 425F11A027M0000 can be used in a wide range of applications, such as industrial, military, aerospace, and medical devices. It is also ideal for use in precision instruments or where accuracy and reliability are essential. It is suitable for use in circuitry from audio frequency (AF) to very high frequency (VHF).

Working principle

Crystals are electronic components that oscillate when voltage is applied to them. An oscillator circuit generally consists of an amplifier, a resistor, a capacitor and the quartz crystal. When a voltage is applied to the crystal, the quartz crystal begins to vibrate at its mechanical resonance frequency, and the resulting vibration will generate an electrical signal. The electrical signal is then amplified, filtered and passed through a resistor and a capacitor. This signal is then output from the oscillator at the exact same frequency as the frequency of the quartz crystal.

The 425F11A027M0000 crystal is constructed using a 32.768 kHz quartz crystal and is sealed in a hermetically sealed ceramic package. This type of crystal is also referred to as a “tuning fork” crystal, due to its shape. The quartz crystal inside the crystal oscillates at its mechanical resonance frequency, which is determined both by the properties of the quartz and the design of the crystal. The frequency of the quartz crystal is usually set by the manufacturer and is not adjustable.
