The ECS-184-20-3X-TR is a surface mount quartz crystal in the CSM-3X series, designed for compact PCB applications with a reduced footprint compared to the CSM-7X. It operates at 18.432 MHz with a load capacitance of 20 pF, has a fundamental mode of oscillation, and a maximum equivalent series resistance of 60 Ω. The operating temperature range is -10°C to +70°C, with frequency stability of ±50 ppm over this range and a frequency tolerance of ±30 ppm at +25°C. The device is RoHS compliant, has a shunt capacitance of 7 pF, and a maximum drive level of 100 µW. It uses a resistance weld package with a suggested reflow profile peaking at +260°C for no more than 10 seconds over two cycles, and is supplied in tape and reel packaging. Pin connections are symmetrical and interchangeable.
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.
