ECS-.327-12.5-12-TR Description

Short technical summary and product information.

The ECS-.327-12.5-12-TR is a 32.768 kHz tuning fork crystal designed for low-power real-time clock (RTC) applications. It offers a nominal frequency of 32.768 kHz with a frequency tolerance of ±20 ppm at +25°C. The crystal requires a 12.5 pF load capacitance and exhibits a maximum equivalent series resistance (ESR) of 90 kΩ. Operating from -40°C to +85°C, it provides stable performance over a wide temperature range. The device is housed in a compact 2.00mm x 1.20mm x 0.60mm 2-SMD ceramic package with gold termination, suitable for surface mount assembly. It is supplied on tape and reel in quantities of 3000 pieces per reel. The ECX-12 series is RoHS3 compliant and has an MSL rating of 1 (unlimited). Typical applications include IoT devices, industrial controls, automotive electronics, and battery-powered systems.
