Crystals are an essential component in electronic devices, and in the application fields of ultra-short wave, RF, microwave and digital circuits, they have functional uses. The HC-49/U-S12000393ABJB crystal is one of the crystals used in such circuits.

The HC-49/U-S12000393ABJB crystal is a miniature device, featuring a diameter of only 4.25mm and a height of only 2.2mm. It has a frequency range of 12.000160 to 12.000202 MHz and uses a composite quartz blank, making it more stable and accurate than other small crystals. With its low profile and wide frequency range, this crystal is ideal for use in high-density circuits, such as small size wireless applications.

The HC-49/U-S12000393ABJB crystal works on the principle of piezoelectric effect. This effect is used to generate a stable, high-precision output frequency, using a quartz blank or other crystal material for converting an electrical signal into an acoustic one. When an alternating voltage is applied to the quartz blank, it vibrates at a frequency determined by the quartz crystal; and when the voltage is cut off, the vibration returns to its original frequency. This process is then repeated in order to maintain the output frequency in a stable range.

The quartz blank used in the HC-49/U-S12000393ABJB crystal is made up of a 26MHz and a 48MHz quartz blank, providing current and voltage amplification in the device. In addition, this quartz crystal also features a built-in capacitor integrated into the quartz blank, further stabilizing the output frequency. The capacitor also acts as an anti-resonance circuit, eliminating any excessive resonances in the working frequency range.

The HC-49/U-S12000393ABJB crystal is used to precisely control the frequency in applications such as modems, cell phone repeaters, Bluetooth, car audio systems, plane communication, SHF communication, and transceivers. It is also used in military communication systems and satellite communications. This crystal is currently used in a wide range of applications and is highly reliable in terms of stability and accuracy.

The HC-49/U-S12000393ABJB crystal is a cost-effective and compact solution for applications where high-frequency accuracy and stability are essential. With its low profile, wide frequency range and integrated capacitor, this crystal provides a stable, accurate and cost-effective solution for a variety of electronic applications.
