The CSM-7XDU is a surface mount crystal oscillator with an operating temperature range of -55°C to +125°C and frequency stability of ±100 ppm over that range. It supports frequencies from 3.57 MHz to 70.000 MHz, with equivalent series resistance ranging from 30 Ω to 150 Ω depending on frequency and oscillation mode. Shunt capacitance is 7 pF, maximum drive level is 500 μW, and load capacitance is specified as 10 pF, 20 pF, or series. Aging is ±5 ppm over the first year at +25°C. The package is a low-profile SMD design compliant with RoHS standards, with a suggested reflow profile peaking at +260°C for up to 10 seconds and an MSL rating of 1. The part number identifies frequency, load capacitance, package, temperature stability, and packaging type.
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.
