B39431R0990H110

Introduction

A B39431R0990H110 resonator belongs to a family of devices known as high-Q piezoelectric filter resonators. This type of resonator is composed of two parts separated by a central high-Q piezoelectric element. The lower part is made of a dielectric material and acts as the primary resonator element. The upper part is composed of a thin layer of the same dielectric material and acts as a secondary resonator element. The two parts together form an acoustic filter, which is typically used for frequency or noise control.

Application Field

B39431R0990H110 resonators are used in a variety of electronic applications such as radio frequency (RF) electronic systems, television receivers, audio systems, and industrial equipment. In RF applications, this type of filter is commonly used to reduce interference from external sources. It can also be used in telephone systems to eliminate unwanted noise and improve voice quality. In television receivers, this type of filter may be used to reduce interference and improve the picture quality. It can also be used in audio systems to reduce noise and improve sound quality.

Working Principle

B39431R0990H110 resonators operate by a principle known as piezoelectricity. This involves the conversion of mechanical energy into electrical energy and vice versa. The lower part consists of a piezoelectric element that vibrates at a specific frequency when a voltage is applied to it. The upper part has a dielectric material that acts as a filter and is tuned to the same frequency as the piezoelectric element. When external energy in the form of RF or audio is present, the lower part vibrates, and the upper part prevents the energy from passing through.

In conclusion, B39431R0990H110 resonators are a type of high-Q piezoelectric filter resonators that are used in applications such as RF systems, television receivers, audio systems, and industrial equipment. They work by converting mechanical energy into electrical energy and vice versa, with the lower part consisting of a piezoelectric element that vibrates at a specific frequency, and the upper part containing a dielectric material that acts as a filter and is tuned to the same frequency.
