This is a 27 MHz quartz crystal from ECS Inc. in the ECX-53B surface mount package. It is designed for series resonant operation with no external load capacitance required. The crystal offers a frequency tolerance of ±30 ppm at 25°C and frequency stability of ±50 ppm over the operating temperature range of -20°C to +70°C. The equivalent series resistance (ESR) is 30 Ω maximum for the 24-50 MHz range, with a typical drive level of 100 μW.
The crystal operates in fundamental mode and has a shunt capacitance of 5 pF typical. The package dimensions are 5.00 mm x 3.20 mm x 0.85 mm, with gold-plated terminals. It is RoHS compliant and rated MSL 1 (unlimited floor life). The part is supplied in tape and reel packaging with 1000 pieces per reel, suitable for automated assembly.
This crystal is ideal for compact wireless applications, IoT devices, and other space-constrained designs requiring a stable clock source. Its low profile and industry-standard footprint facilitate easy integration into PCB layouts.
