The ECS-147.4-20-4 is a 14.7456 MHz quartz crystal from ECS Inc., housed in a low-profile HC-49US through-hole package. It operates in fundamental mode with a maximum equivalent series resistance (ESR) of 40 Ω. The crystal offers a frequency tolerance of ±30 ppm at 25°C and a frequency stability of ±50 ppm over the standard operating temperature range of -10°C to +70°C.
Designed for reliable performance, this crystal features a load capacitance of 20 pF and a typical shunt capacitance of 7.0 pF. It supports a drive level of 0.5 mW and exhibits excellent aging characteristics of ±5.0 ppm in the first year. The storage temperature range extends from -40°C to +105°C.
The HC-49US package measures 11.35 mm x 4.65 mm with a seated height of 3.50 mm, making it suitable for space-constrained applications. The resistance weld construction ensures long-term reliability. This crystal is RoHS3 compliant and REACH unaffected.
Typical applications include microprocessors, communication equipment, and general timing circuits requiring a stable 14.7456 MHz reference. The through-hole mounting allows for easy integration into PCB designs.
