The ECX-3SX is a surface mount quartz crystal optimized for compact electronics, featuring a molded thermoplastic package with an industry-standard footprint and low profile. It operates over a frequency range of 3.570 to 70.000 MHz, with a load capacitance of 20 pF, a shunt capacitance of 7.0 pF, and a maximum drive level of 100 μW. Frequency tolerance is ±30 ppm at +25°C, and stability across -10°C to +70°C is ±50 ppm. The device supports fundamental mode oscillation up to 35.999 MHz and third overtone from 27.000 to 70.000 MHz, with maximum ESR values up to 200 Ω. Operating temperature ranges from -10°C to +70°C, with storage temperatures from -40°C to +85°C. It is RoHS compliant, has a maximum reflow peak temperature of +260°C for 10 seconds, and is MSL 1 rated with Sn/Cu 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.
