The ECX-49 is a surface mount tuning fork crystal designed for low-power RTC applications, featuring a 4.1 x 1.5 x 0.9 mm ceramic package with a 4.1 x 1.5 mm footprint. It operates at 32.768 kHz with a load capacitance of 12.5 pF, an equivalent series resistance of 70 kΩ, and a drive level of 1.0 μW. The operating temperature range is -40°C to +85°C, with a storage temperature range of -55°C to +125°C. It has a frequency tolerance of ±20 ppm at +25°C, a temperature coefficient of -0.028 to -0.040 ppm/°C², and an aging rate of ±3 ppm over the first year. The part is RoHS compliant, has a maximum reflow temperature of +260°C for 10 seconds, and is rated MSL 1 with gold lead finish.
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.
