The ECX-53B is a miniature surface mount crystal designed for compact wireless applications, featuring a 3.2 x 5 mm footprint and a standard industry layout with pads 1 and 3 interchangeable. It operates from 8.000 to 50.000 MHz with a fundamental mode of oscillation, supports load capacitances of 8 or 20 pF, and has a maximum drive level of 100 μW. Frequency tolerance at +25°C is ±30 ppm, and frequency stability over the operating temperature range of -20 to +70°C is ±50 ppm. Shunt capacitance is 5 pF, with equivalent series resistance ranging from 30 to 100 Ω depending on frequency. The device is RoHS compliant, meets MSL 1 moisture sensitivity level, and uses gold lead finish. Storage temperature ranges from -55 to +125°C, and aging is ±5 ppm over the first year at +25°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.
