10 Things You Should Know About the HE-49U Crystal Quartz Resonator.
If you're in the market for high-precision crystal oscillators, you might have come across the HE-49U Crystal Quartz Resonator. This device promises stable and accurate timing for your electronic circuit designs. In this article, we'll break down the ten things you should know about the HE-49U Crystal Quartz Resonator, and hopefully help you decide if it's the right component for your needs.
1. It's a Quartz Resonator.
The HE-49U Crystal Quartz Resonator is a type of crystal oscillator that uses the natural frequency of quartz crystal to generate an electrical signal. Quartz has the particularity of being piezoelectric, which means that it can convert mechanical pressure into an electric voltage. In the case of the HE-49U Crystal Quartz Resonator, a small quartz crystal is sandwiched between two metal electrodes. When an electrical current is applied, the crystal vibrates at its natural frequency, generating a very stable and precise signal.
2. It Has a Very High Q-Factor.
The Q-Factor of an oscillator is a measure of its quality or "purity." The higher the Q-Factor, the less energy is lost to other forms, such as thermal or electromagnetic radiation. The HE-49U Crystal Quartz Resonator has an extremely high Q-Factor, which means that it can maintain its oscillation for a long time without losing accuracy.
3. It Operates at a High Frequency.
The HE-49U Crystal Quartz Resonator can operate at a frequency range of 8 MHz to 150 MHz. This makes it suitable for a wide range of applications, from precision timing in computers and communication systems to frequency reference in scientific instruments.
4. It Has a Small Package.
The HE-49U Crystal Quartz Resonator comes in a hermetically sealed, 4-pin HC-49/U package. This package is only 11.05 mm long by 4.65 mm wide by 3.5 mm high, making it easy to integrate into your electronic designs.
5. It's RoHS Compliant.
The Restriction of Hazardous Substances (RoHS) directive sets limits on the use of toxic materials in electronic components. The HE-49U Crystal Quartz Resonator fully complies with this directive, making it safe for the environment and human health.
6. It Has a Wide Temperature Range.
The HE-49U Crystal Quartz Resonator can operate over a temperature range of -40°C to +85°C. This means that it can function in a wide range of environmental conditions, from freezing cold to scorching hot.
7. It Has Low Power Consumption.
The HE-49U Crystal Quartz Resonator has a low power consumption of only 0.003W. This makes it ideal for battery-powered devices or energy-efficient designs.
8. It's Highly Reliable.
The HE-49U Crystal Quartz Resonator has a mean time between failure (MTBF) of over 100,000 hours. This means that you can expect it to operate reliably for a very long time in your electronic circuit.
9. It Has a Low Aging Rate.
Aging is the gradual change in the oscillator's frequency over time. The HE-49U Crystal Quartz Resonator has a low aging rate of only ±5 ppm per year. This means that it can maintain its accuracy over a long time without the need for frequent recalibration.
10. It's Widely Available.
The HE-49U Crystal Quartz Resonator is a popular component in the electronics industry and is widely available from various suppliers. You can contact us if you need help finding a supplier for your HE-49U Crystal Quartz Resonator needs.
