Datasheet
If you want to learn more, please visit our website.
The HC-49SMD is a small, surface-mount quartz crystal that provides precise timing for electronic devices. It operates at a frequency of 8.192 MHz, with a capacitance of 20 pF and a tolerance of ±20 ppm. This means it can deviate by up to 20 parts per million from its ideal frequency.
Here are some of the key features of the HC-49SMD quartz crystal:
- Small size:
The SMD (surface-mount device) package makes it ideal for use in space-constrained applications. - High frequency:
The 8.192 MHz frequency makes it suitable for a wide range of applications, such as clocks, timers, and oscillators. - Stable frequency:
The ±20 ppm tolerance ensures accurate timing.
Quartz Crystals
Apart from our finished quartz frequency control products, Morion manufactures a wide range of crystals of various designs for frequencies ranging from 4 kHz to 200 MHz. For these crystals we employ quartz elements manufactured along the most commonly used cuts. Morion offers the crystals in standard HC-52, HC-49 and HC-33 packages.
