The ECS-40-20-19A-TR is a 4.000 MHz fundamental mode quartz crystal from ECS Inc., part of the ECX-19A series. It features a frequency tolerance of ±30 ppm at +25°C and frequency stability of ±50 ppm over the -10°C to +70°C operating temperature range. The crystal is designed for a load capacitance of 20 pF and has a maximum equivalent series resistance (ESR) of 150 Ω at 4 MHz.
This surface mount crystal comes in a compact 2-SMD, no lead package measuring 11.00 mm x 5.00 mm x 2.00 mm. It is supplied on tape and reel with a standard package quantity of 1000 pieces. The lead finish is gold (Au), and the device is RoHS3 compliant and lead-free.
Typical applications include clock generation for microcontrollers, timing circuits, and communication interfaces where a stable 4 MHz reference is required. The fundamental mode of oscillation ensures reliable performance without overtone complications.
