The ECS-.327-12.5-34B-TR is a low-profile SMD tuning fork crystal from ECS Inc.'s ECX-31B series. It operates at a nominal frequency of 32.768 kHz with a frequency tolerance of ±20 ppm at +25°C. The crystal requires a load capacitance of 12.5 pF and has a maximum equivalent series resistance of 70 kΩ.
Designed for surface mount applications, this crystal is housed in a compact 2-SMD, No Lead ceramic package measuring 3.2 x 1.5 x 0.9 mm. It operates over an industrial temperature range of -40°C to +85°C and is RoHS compliant with MSL Level 1. The drive level range is 0.1 μW to 1.0 μW, making it suitable for low-power real-time clock circuits.
The crystal features gold termination finish and is supplied in tape and reel packaging with a standard quantity of 3,000 pieces. It is commonly used in RTC applications such as STM32 microcontrollers, offering reliable timekeeping with aging of ±3 ppm in the first year.
