The ECX-34RR is a surface mount tuning fork crystal designed for low-power RTC applications, particularly with STM32 microcontrollers. It operates at 32.768 kHz with a load capacitance of 12.5 pF and a typical equivalent series resistance of 20 kΩ. The component features a 3.2 mm × 1.5 mm footprint, operates over a temperature range of -40°C to +85°C, and has a turnover temperature of +20°C to +30°C. It meets RoHS compliance, has an insulation resistance of 500 MΩ at 100 V DC, and is rated for reflow soldering up to +260°C for 10 seconds. The shunt capacitance is 1.3 to 1.6 pF, and the aging rate is ±3 ppm over the first year at +25°C ±3°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.
