402F20022IKT application field and working principle

The 402F20022IKT is part of the Piezoelectric Product Line of Passive Components from Tokin Corporation. It is a type of piezoelectric component called Film Bulk Acoustic Resonators, which are components that can be used for frequency control, choice, and filtering. They use the physical property of quartz crystals to generate oscillating electrical signals.

Piezoelectric crystal is a type of material in which energy is converted into mechanical vibration or electrical current when stimulated. The electrical energy drives the mechanical vibration, which generates an acoustic wave. Tokin Corp’s 402F20022IKT is made of quartz crystal, which is the best type of crystal material for piezoelectric applications due to its high frequency stability and low acoustic loss.

By combining this crystal with electrically conductive electrodes, Tokin Corp created their 402F20022IKT. With two electrodes surrounding the crystal, an electrical current is applied to one of the electrodes, exciting the crystal and creating wave vibrations in the material. These wave vibrations travel through the crystal at different frequencies, depending on the shape and size of the crystal, and are then picked up by the second electrode as an electrical signal.

The 402F20022IKT thus acts as a filter, allowing only signals at specific frequencies to pass through from an input signal to the output. This makes it ideal for use in a variety of applications – radio frequency communication systems and telecommunication networks, for example, require the frequency selection and filtering capabilities of the 402F20022IKT for operation. Other applications include audio amplifiers, modulators, and even medical equipment.

The primary advantage of using quartz crystals for frequency selection is their excellent stability over a wide temperature range and long periods of time. The 402F20022IKT has been designed to be highly reliable, withstanding temperatures between -40˚C and +85˚C, allowing it to be used in a variety of extreme environments. By controlling the size and shape of the crystal, Tokin Corp has been able to effectively create a filter with a very high frequency accuracy, low electrical loss, and low phase noise.

Clearly, the 402F20022IKT from Tokin Corp is an incredibly versatile component that is designed for optimal performance. Its ability to filter out unwanted frequencies, combined with its excellent frequency accuracy and wide temperature range, make it a powerful tool for frequency control, selection, and filtering in a range of applications.
