The CWX813-4 oscillator from Connor-Winfield Corporation is a surface-mount device designed for use in compact, high-reliability applications. These oscillators operate at a nominal frequency of 3.3V and offer ±25 PPM frequency stability, making them ideal for precision timing requirements in modern electronics. If you're working on designs that demand stable clock signals without taking up too much board space, these oscillators are a solid choice.

One thing worth noting is their surface-mount design, which simplifies assembly and reduces the overall footprint of your circuit. This makes them particularly appealing for space-constrained applications like smartphones, wearables, and IoT devices. Another practical observation is their ±25 PPM frequency stability, which is quite respectable and ensures consistent performance over temperature variations. Engineers tend to reach for this when they need a reliable clock source that doesn’t require external calibration or tuning. The 3.3V supply voltage is also convenient, aligning well with many digital circuits operating at this voltage level. Overall, the CWX813-4 offers a good balance of performance and form factor, making it a valuable component in a wide range of projects.
