Application Field

The ECS-240-20-18-TR has a number of applications across a variety of industries. It is particularly suited to applications where low power, low jitter and high stability are essential, such as in medical imaging systems. It is also used in audio equipment and mobile phones, where accuracy and reliability are paramount.

The ECS-240-20-18-TR can also be used in automotive systems, including engine control, ABS and airbag systems. Additionally, it is suitable for use in electronic timepieces, such as clocks and watches. It is even used in military and space applications, where extreme accuracy and durability are essential.

Working Principle

At the heart of the ECS-240-20-18-TR is a quartz crystal, which works through the piezoelectric effect. When a voltage is applied across the crystal, it distorts in shape and produces an electric current. It will then oscillate in response to the applied voltage, producing an alternating electric current. This current can be used to generate a timing signal.

When the crystal is temperature-compensated, it is designed to maintain a steady frequency over a range of temperatures. This is achieved by adjusting the crystal’s electrical characteristics, such as its capacitance, which alters its frequency in response to temperature changes.

The ECS-240-20-18-TR is also equipped with a thermosiphon, which helps to stabilise the output signal by stabilising the temperature of the crystal. This allows it to maintain a steady signal despite changes in the ambient temperature.
