ECS-.327-12.5-12R-TR Description

Short technical summary and product information.

The ECS-.327-12.5-12R-TR is a surface-mount tuning fork crystal designed for low-power real-time clock (RTC) applications. It operates at a frequency of 32.768 kHz with a frequency tolerance of ±20 ppm at +25°C. The crystal has a load capacitance of 12.5 pF and a maximum equivalent series resistance (ESR) of 70 kΩ. It is rated for a drive level of 1.0 µW and exhibits a shunt capacitance of 1.3 pF. The temperature coefficient is -0.036/-0.033/-0.030 ppm/°C² with a turnover temperature range of +20 to +30°C. Aging is specified at ±3 ppm maximum in the first year. The operating temperature range is -40°C to +85°C, with storage from -55°C to +125°C. The crystal is housed in a 2-SMD, No Lead ceramic package measuring 2.00mm x 1.20mm x 0.60mm. It is RoHS3 compliant, REACH unaffected, and has an MSL of Level 1 (unlimited). The part is supplied on tape and reel with a standard quantity of 3000 pieces per reel. Typical applications include metering, automotive, industrial, IoT, and wearable devices where low power and small footprint are critical.
