ECS Inc. International Surface Mount Crystals ECS-250-18-5PXDN-TR

The CSM-7XDN is an industrial-temperature range surface mount crystal designed for stable oscillation in demanding applications. It is housed in a standard SMD package with a symmetrical footprint and measures 4.3 mm in length. The device operates over a temperature range of -40°C to +85°C and supports frequencies from 3.57 MHz to 70.000 MHz, with frequency stability of ±100 ppm across this range. Drive level is limited to 500 μW maximum. Equivalent series resistance ranges from 30 Ω to 150 Ω depending on frequency and mode, with 3rd overtone operation used above 40 MHz. Load capacitance must be specified in the part number from 10 pF or 20 pF options. It meets RoHS compliance standards and has a storage temperature range of -55°C to +125°C. Aging is specified at ±5 ppm over the first year at +25°C.
