CM309A3 crystals and oscillator Series

citizen

The CM309A3 crystal series from Citizen Watch Co., Ltd. is a line of surface-mount crystals designed for precise timing applications. These crystals feature an 18pF load capacitance, which makes them suitable for a variety of embedded systems where space is limited and high accuracy is required. If you're working on projects involving microcontrollers, FPGA boards, or any digital circuitry that needs reliable timing, these crystals could be a great fit. One thing worth noting is that the compact size of these surface-mount crystals makes them ideal for small form factor designs. They are commonly used in portable electronics, IoT devices, and medical equipment where minimizing the overall footprint is crucial. Another practical application is in automotive systems, where the stability and reliability of the timing signal are paramount. Engineers tend to reach for this when they need a precise timing reference that can be easily integrated into a PCB without taking up too much space. The 18pF load capacitance is a good middle ground, providing a balance between performance and ease of use. Overall, the CM309A3 crystals offer a reliable solution for timing applications in a wide rang
