The ECS-.327-12.5-17X-C-TR is a compact SMD tuning fork crystal operating at a frequency of 32.768 KHz. It is designed with a specified load capacitance of 12.5 pF and a frequency tolerance of ±10 ppm at +25°C. This component features a maximum equivalent series resistance (ESR) of 50 kΩ and a maximum drive level of 1.0 µW. Housed in a 3.8 x 8.0 x 2.5 mm ECX-306X package, it operates reliably over an extended temperature range of -40°C to +85°C. Its stability and low power consumption make it ideal for RTC applications, communications, and measuring equipment.
