402F32011CLT

The 402F32011CLT is a type of crystal unit which is used extensively in many consumer and medical electronics applications. It is a small, low power, quartz crystal oscillator designed for use in applications where high accuracy and stability are required. The quartz crystal used in the 402F32011CLT has a frequency tolerance of less than 10 parts per million (ppm), making it one of the most accurate crystals available for consumer and medical electronics applications.

The 402F32011CLT is composed of a quartz crystal encased in a metal can and connected to a pair of resistors. The crystal is the active element of the oscillator and operates by responding to electrical energy, producing an alternating electrical current at its resonant frequency.

The two metal contacts on the crystal leave an air gap between them. This air gap is known as the "active gap" and is maintained by the metal can. When a voltage is applied across the active gap, the atom located at this gap vibrate at a specific frequency. This frequency is known as the crystal\'s resonant frequency - the frequency at which the crystal will naturally oscillate at.

The quartz crystal used in the 402F32011CLT has a limited frequency range, spanning from 1~62.6MHz. When operated at its resonant frequency, the crystal is extremely stable and accurate, offering a temperature stability of ±10ppm over a temperature range of -20°C to +70°C.

In addition to its extremely high accuracy and stability, the 402F32011CLT offers a low drive requirement; only 2.5mA of current is needed to drive the crystal while still providing good performance. This makes it an ideal choice for applications which have limited power available.

The 402F32011CLT is used in many applications including television receivers, video recorders, medical instrumentation and computer peripherals. It is often used to generate clocks for a variety of microprocessor based systems such as for automotive electronics, digital cameras and even for applications in aerospace computing.

The 402F32011CLT is a well-designed crystal unit which offers excellent accuracy and stability, a very wide frequency range, and a low current drive requirement. It is a cost effective solution for many consumer and medical electronics applications and can provide the stability and accuracy needed for reliable operation.
