EPSON FC-135 SMD Crystal, 32.768kHz, 12.5pF, 20ppm, 3.2mm x 1.5mm

The EPSON FC-135 series is a low-profile SMD (Surface-Mount Device) crystal unit engineered for precision timing applications. Operating at a fundamental frequency of 32.768kHz, it provides the stable and accurate clock signal essential for real-time clocks (RTCs), microcontrollers, and various digital circuits. Its compact footprint of 3.2mm x 1.5mm makes it an ideal choice for space-constrained, modern electronic designs where board real estate is at a premium.

This crystal is characterised by a tight frequency tolerance of ±20ppm (parts per million), ensuring reliable and consistent performance across its specified operating range. It is designed with a load capacitance of 12.5pF, which is critical for engineers to match in their oscillator circuit design to achieve the specified frequency accuracy. The unit is supplied in a standard two-pin SMD package, facilitating easy automated assembly and soldering in high-volume production environments.

Built to withstand demanding conditions, the FC-135 operates reliably across a broad temperature range from -40°C to +85°C. This robustness makes it suitable not only for consumer electronics but also for more challenging applications in industrial automation and automotive systems, where components must perform under extreme thermal stress.
