The CWX813-1 series from Connor-Winfield Corporation is a line of 3.3V surface-mount crystal oscillators designed for precision timing applications. These oscillators offer ±25ppm frequency stability over temperature, which makes them ideal for environments where temperature fluctuations might affect timing accuracy. If you're working on projects that require reliable and stable clock signals, especially in smaller form factors, these oscillators are a great fit.

One thing worth noting is their compact size; being surface-mount components, they integrate seamlessly into modern PCB designs without taking up too much space. This makes them particularly useful in high-density applications such as consumer electronics, medical devices, and industrial control systems where space is at a premium but precision timing is crucial.

Engineers tend to reach for this when they need a stable clock source that doesn’t require external tuning or calibration, and can operate within a small form factor. The ±25ppm stability ensures that these oscillators maintain their accuracy even under varying environmental conditions, making them a robust choice for a wide range of applications.
