The ECX-71 is a surface mount tuning fork crystal designed for low-power RTC applications such as STM32 microcontrollers. It features a plastic package measuring 7 x 1.5 x 1.4 mm with a 7 x 1.5 mm footprint. The device operates at 32.768 kHz with a frequency tolerance of ±20 ppm at +25°C and a load capacitance of 12.5 pF. It has an equivalent series resistance of 65 kΩ, a drive level of 0.1 to 1.0 μW, and an operating temperature range of -40 to +85°C. The turnover temperature is +20 to +30°C, with a temperature coefficient of -0.025 to -0.045 ppm/°C². Aging is ±3 ppm over the first year at +25°C. The shunt capacitance is 0.8 pF. The part is RoHS compliant, has MSL 1, and a lead finish of Sn. The storage temperature range is -55 to +125°C.
ECS Inc.’s surface mount (SMD) crystals provide users with a solution that yields long-term stability and reliability for a myriad of applications. Surface mount capabilities allow your device to be packaged with the leads soldered directly to the pads of the circuit board surface. Supplied at both custom and standard frequencies, SMD crystals are ideal for applications such as: microprocessors, internet of things (IoT), including GPS systems and smart home security systems, automotive computers and components, wearable technologies, like smartwatches, Wi-Fi, connectivity and more.
