The ECX-3SX is a surface mount quartz crystal designed for general-purpose applications requiring stable frequency control. It comes in a molded SMD package with an industry-standard footprint and low profile, supporting frequencies from 3.570 to 70.000 MHz. The crystal operates over a temperature range of -10°C to +70°C with a frequency stability of ±50 ppm, and a load capacitance of 20 pF as specified in the part number. Maximum equivalent series resistance ranges from 50 Ω to 200 Ω depending on frequency and mode of oscillation, with overtone operation above 27 MHz. It has a shunt capacitance of 7.0 pF, a drive level of 100 μW, and aging of ±5 ppm in the first year at +25°C. The device is RoHS compliant, has an MSL rating of 1, and a storage temperature range of -40°C to +85°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.
