The C3E-24 series from Aker Technology Co., Ltd., is a line of compact surface-mountable (SMD) ceramic resonators designed for use in microprocessors operating in the 24-24.576 MHz range. These components are specified to have a frequency stability of ±30-50 ppm, which is crucial for maintaining accurate timing in high-speed digital circuits.

These resonators typically find their way into a variety of projects and systems, including embedded systems, networking equipment, and consumer electronics that require precise clocking. If you're working on any system where timing accuracy is critical, such as real-time control systems or high-frequency communication devices, these ceramic crystals can be a reliable choice.

One thing worth noting is their small form factor. Given their SMD design, they can be easily integrated into densely packed PCB layouts without taking up too much space. This makes them particularly useful in portable devices or modules where board space is at a premium.

Engineers tend to reach for this when they need a stable clock signal in a constrained environment, and the ±30-50 ppm stability is more than sufficient for many applications. They also benefit from the reliability and longevity associated with ceramic resonators, which can withstand harsh environmental conditions better than some other types of oscillators.
