The ECS-400-20-3X-EN-TR is a surface mount quartz crystal in the CSM-3X series, designed for compact circuit board mounting. It features a low-profile resistance weld package with a footprint 50% smaller than the CSM-7X. The part operates from 12.000 to 40.000 MHz in fundamental mode with a load capacitance of 20 pF, a maximum drive level of 100 μW, and frequency stability of ±50 ppm over the operating temperature range of -10°C to +70°C. It has a shunt capacitance of 7 pF and an equivalent series resistance of 40 Ω maximum at 40.000 MHz. The device is RoHS compliant, has a storage temperature range of -40°C to +85°C, and is rated for reflow soldering with a peak temperature of +260°C for 10 seconds maximum over two cycles. Pin connections are interchangeable. The part is supplied in tape and reel packaging (3K/reel).
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.
