The ECS-.327-12.5-12-C-TR is a surface-mount tuning fork crystal providing a precise 32.768 KHz frequency reference. This component is specified with a load capacitance of 12.5 pF and a frequency tolerance of ±10 ppm at +25°C. Housed in a miniature 2.0 x 1.2 mm ceramic package, it operates reliably across an extended temperature range of -40°C to +85°C. Its compact footprint and suitability for low-power RTC applications make it an excellent choice for IoT devices, real-time clocks, automotive systems, and industrial controls.
