ECS Inc. International Surface Mount Crystals ECS-245.7-18-5PXEN-TR

The ECS-245.7-18-5PXEN-TR is a surface mount crystal from the CSM-7X series, designed for stable oscillation in compact electronic designs. It uses a resistance-weld metal package with a case height of 4.3 mm maximum (5PX variant) and an industry-standard footprint. The part operates from -10°C to +70°C with a frequency tolerance of ±30 ppm at +25°C and frequency stability of ±50 ppm over the operating range. It supports 24.57 MHz operation in fundamental mode with a maximum equivalent series resistance of 40 Ω and a load capacitance of 18 pF. Drive level is rated at 500 μW maximum, and the crystal is RoHS compliant with a Sn/Cu matte lead finish. Storage temperature ranges from -55°C to +125°C, and aging is ±5 ppm over the first year at +25°C ±3°C. The part is supplied in tape and reel packaging.
