The ECS-.327-7-34B-TR is a surface mount tuning fork crystal from ECS Inc.'s ECX-31B series. It operates at a frequency of 32.768 kHz with a load capacitance of 7 pF and an equivalent series resistance of 70 kΩ. The crystal has a frequency tolerance of ±20 ppm and a temperature coefficient ranging from -0.040 to -0.028 ppm/°C², ensuring stable operation over the -40°C to +85°C temperature range.
Designed for low-power timekeeping applications, this crystal operates in fundamental mode and requires a drive level between 0.1 μW and 1.0 μW. It features a shunt capacitance of 1.05 pF and an insulation resistance of 500 MΩ minimum. The first-year aging is limited to ±3 ppm, and the storage temperature range extends from -55°C to +125°C.
The crystal is housed in a compact 3.2 mm x 1.5 mm x 0.9 mm 2-SMD no-lead ceramic package, suitable for high-density PCB designs. It is supplied on tape and reel with a standard quantity of 3000 pieces per reel. The lead finish is gold (Au) and the component is rated MSL 1 (unlimited) for moisture sensitivity.
This component is RoHS compliant and is commonly used in real-time clock (RTC) circuits, such as those found in microcontroller applications like STM32 reference designs. Its low power consumption and small footprint make it ideal for battery-powered portable devices.
