Description
HC-49US series ceramic resonators are an electronic component consist of a piece of a high-stability piezoelectric ceramic material with two metal electrodes attached, manufactured by YXC. When crystals are connected to an electronic oscillator circuit, resonant mechanical vibrations in the device generate an oscillating signal of a specific frequency. These crystals are often used in place of quartz crystals as a clock/signal generator in electronic circuitry because their size is smaller and the cost is very low.
