416F25033CDT

Introduction

The CGDT 43F25033CDT is a ceramic resonator commonly used in frequency control applications. It is composed of a quartz vibrator, a parallel resonant circuit and mechanical or electrical contacts for operation with the quartz vibrator, and it is installed in a hermetically sealed metal can to provide electrical insulation and long-term stability and reliability.

Application field

The CGDT 43F25033CDT is primarily used in frequency control applications, such as frequency converters, sweepers and modulators, and quartz crystal oscillators. It is also used in precision power supplies, radio transceivers, and radio and television receivers.

Working Principle

The CGDT 43F25033CDT uses an electrical-mechanical oscillating charging circuit to convert an input voltage of resonant, harmonic, or a combination of these frequencies into an output voltage, the output frequency being proportional to the resonant frequency of the quartz crystal element.The CGDT 43F25033CDT has a long-term frequency stability due to the quartz resonator which is hermetically sealed in a metal container and mechanically and electrically isolated from the environment. The quartz resonator is also referred to as a Thin-Film Crystal (TFC). The TFC consists of a metal metalization layer, a piezoelectric layer, and an electrode to form a switch that is activated by the input voltage.When the voltage is applied to the quartz crystal, the TFC vibrates with the applied voltage and causes a cyclic charge redistribution through the quartz crystal that produces an alternating electric field. The alternating electric field causes the quartz crystal element to vibrate, creating an oscillating voltage across the electrodes. The output frequency is proportional to the resonant frequency of the quartz crystal element.
