SMD 7.0×5.0 High-Precision Industrial Aautomation Crystal Oscillator
product application
Industrial grade crystal is generally used for industrial control panels, automotive electronic equipment and other vulnerable to external instability, poor working environment or difficult to locate products, to make the best use effect and long-term reliability, in the final process of stability.
product features
Industrial grade crystal commonly known as: wide temperature high temperature crystal, crystal and so on, is that in industrial grade crystal, at least the working temperature than the civilian level of -20 - 70 degrees wide, its working temperature is -40 and 85 C, chip cutting type is BT, these two points is very critical.
product advantage
Industrial grade crystal have higher precision, stronger anti oscillation function and stability, wide temperature range, high temperature resistance.
