The PE8845 series from Pletronics, Inc., is a lineup of standard clock oscillators designed for applications requiring precise timing. These oscillators operate at a stable 3.3V output and maintain a frequency accuracy of ±50ppm over their specified temperature range. They come in different versions tailored to various temperature coefficients, making them suitable for a wide range of projects and systems.

If you're working on embedded systems, networking equipment, or any device that relies on accurate timekeeping, these oscillators are a go-to choice. Their stability and reliability make them ideal for environments where temperature fluctuations might affect performance. One thing worth noting is that they are commonly used in industrial control systems, medical devices, and automotive electronics where timing precision is critical. Engineers tend to reach for this type of component when they need a cost-effective solution that still meets stringent timing requirements without the complexity of more advanced oscillators.
