Crystals
Crystals are commonly used in a wide range of applications, in both engineered and naturally occurring forms. Most people are familiar with quartz, which is an important piezoelectric material. Many everyday items such as clocks, watches, microphones, and radio communication systems use crystals to maintain very precise timing.One type of crystal used in the radio communication industry is the 402F24011CDR. This crystal is used in radio frequency transceiver applications, and is able to generate very stable, exact frequencies over a wide temperature range. It also provides excellent reliability and stability.
 
402F24011CDR Application Field and Working Principle
The 402F24011CDR crystal functions as an oscillator that is used to convert direct current (DC) electric power into alternating current (AC) electric power. It is the most important component in the transmitter or receiver in a radio frequency communication circuit. This crystal allows for precise and stable generation of an oscillating signal at a specific frequency.
The 402F24011CDR is designed for use in transceivers that operate in a frequency range from 350 to 450 MHz. It has an operating temperature range from -30 to +85 degrees Celsius. This crystal provides a frequency stability range of +/-25 ppm over this temperature range. It also features extremely low power consumption of 7 mW maximum.
The 402F24011CDR has a highly reliable, 8 pad narrow SMD package, which provides excellent RF performance. This makes it a very attractive choice for radio communication systems that need tight integration and/or low profile designs.
The 402F24011CDR works on the principle of piezoelectricity. The material used to make the crystal, quartz, has piezoelectric properties that provide stability and precision to the frequency of the oscillations. When a voltage is applied to the quartz crystal, it starts to vibrate, creating an oscillating electric current. The frequency at which the quartz vibrates is determined by the physical shape of the crystal.
The basic structure of the 402F24011CDR crystal consists of two metal electrodes separated by a quartz disc. The electrodes are connected to external electronic components that are used to control the oscillation frequency. The mechanical properties of quartz, along with the electrical components connected to the electrodes, allow for precise tuning and control of the oscillation frequency generated by the crystal.
 
The 402F24011CDR is an excellent choice for applications that require stable and precise communication frequencies over a wide temperature range. Its small size and low power consumption make it very appropriate for designs that require tight integration and/or low profile designs. This crystal is a dependable, cost-effective choice for radio communication systems that operate in the range of 350 to 450 MHz.
