ECS-250-20-33-DU-TR Application Field and Working Principle

Crystals are an extremely abundant material found in nature and have many applications. The ECS-250-20-33-DU-TR crystal is one example of how versatile crystals can be and their applications. The ECS-250-20-33-DU-TR is a small, low-cost crystal used in timing applications where high accuracy is not necessary. It is mainly used in low-cost, low-power applications such as calculators, automotive electronics, and simple sound-emitting toys. This article will discuss the application field and working principle of the ECS-250-20-33-DU-TR crystal.

Application

The ECS-250-20-33-DU-TR is mainly used in low-cost, low-power applications such as calculators, automotive electronics, and simple sound-emitting toys. It is often used for timing applications where accuracy is not a major factor. This is because the crystal has a frequency tolerance of less than ±20 parts per million, meaning that it can only keep time to a certain degree of precision. The low cost of the crystal also makes it attractive for low-cost applications.

The ECS-250-20-33-DU-TR is also well suited to applications where high levels of stability are needed. It has a tight stability over temperature and can maintain its external stability over a wide operating temperature range which is typically between -20°C and +70°C. Additionally, it has a high frequency coefficient and a low aging rate, meaning that it is able to maintain its external stability over time.

The small size of the fourth overtone ECS-250-20-33-DU-TR crystal also contributes to its use in low-cost, low-power applications. It is only 2.5x2x1.5mm in size and weighs only 0.079g, meaning that it is ideal for applications where space and weight are important considerations.

Working Principle

The ECS-250-20-33-DU-TR crystal is a piezoelectric crystal. Piezoelectricity is the interaction between a material and an electric field that causes the material to change shape. In the case of the ECS-250-20-33-DU-TR, an electric field causes the crystal to vibrate at a specific frequency. This frequency is determined by the crystal\'s own physical characteristics, as well as by external factors such as the supply voltage.

The ECS-250-20-33-DU-TR crystal is a four overtone crystal, meaning that it has four resonant points. These resonant points are determined by the crystal\'s own physical characteristics. At each resonant point the crystal\'s frequency will be different, depending on the strength of the external electric field. These resonant points can be used for timing applications, as the frequency of the crystal can be changed by changing the external electric field.

The frequency of the ECS-250-20-33-DU-TR crystal is determined by the supply voltage and the size of the external electric field. As the supply voltage increases, the crystal\'s frequency will increase and as the size of the external electric field decreases, the frequency will decrease. This allows for precise timing applications as the frequency of the crystal can be accurately controlled.

Conclusion

The ECS-250-20-33-DU-TR crystal is a small, low-cost crystal with many applications in low-cost, low-power applications such as calculators, automotive electronics, and simple sound-emitting toys. It is a four overtone piezoelectric crystal that is able to resonate at specific frequencies determined by the supply voltage and the size of the external electric field.

The small size and low-cost of the fourth overtone ECS-250-20-33-DU-TR crystal make it an attractive choice for low-cost, low-power applications requiring precise timing. Additionally, its tight stability over temperature, high frequency coefficient, and low aging rate make it well suited to applications requiring high stability over time.
