The ECX-31B is a surface mount tuning fork crystal designed for low-power RTC applications, featuring a 3.2 x 1.5 x 0.9 mm ceramic package and a 32.768 kHz frequency with ±20 ppm tolerance at +25°C. It operates across a temperature range of -40°C to +85°C, has a shunt capacitance of 1.05 pF, a load capacitance of 12.5 pF, and a maximum drive level of 1.0 μW. The equivalent series resistance is 70 kΩ, with an insulation resistance of 500 MΩ at 100 V DC. The part is RoHS compliant, has an MSL rating of 1, and uses gold finish leads. The turnover temperature ranges from +20°C to +30°C, with an aging rate of ±3 ppm in the first year at +25°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.
