The ECX-34Q is a compact SMD tuning fork crystal with a 3.2 x 1.5 mm footprint, designed for low-power RTC applications such as STM32 microcontrollers. It operates from -40°C to +125°C, has a nominal frequency of 32.768 kHz, a load capacitance of 9 pF, a frequency tolerance of ±10 ppm at +25°C, and an equivalent series resistance of 70 kΩ. The device is AEC-Q200 qualified, RoHS compliant, and produced under TS16949 certification. It has a drive level of 0.1 to 0.5 µW, shunt capacitance of 1.1 pF, and motional capacitance of 3.5 fF. The part uses a gold lead finish, is MSL 1 rated, and supports a peak reflow temperature of +260°C for up to 10 seconds in two cycles max.
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.
