Datasheet
Datasheet Summary
Powered by GS/AI

The ECS-.327-12.5-34RR-TR is a surface mount tuning fork crystal for low-power RTC applications, designed for use with STM32 microcontrollers. It operates at 32.768 kHz with a load capacitance of 12.5 pF, a typical equivalent series resistance of 20 kΩ, and a drive level of 0.1 to 0.5 μW. The component has a 3.2 x 1.5 mm footprint, operates from -40 to +85 °C, and meets RoHS compliance. It features a quality factor of 20K to 30K, shunt capacitance of 1.3 to 1.6 pF, and motional capacitance of 3.8 fF. The part supports a maximum reflow peak temperature of +260°C for up to 10 seconds with MSL 1 rating and gold lead finish.
