ECX-1247 SMD Crystals

ECS ECX-1247 SMD Crystals are compact sub-miniature surface-mount crystals that operate at a 24MHz to 80MHz frequency range. These crystals provide a maximum equivalent series resistance (ESR) range of 50Ω to 100Ω at a 24MHz to 80MHz frequency range. The ECX-1247 series offers ±20ppm frequency tolerance at +25°C and ±20ppm frequency stability at -40°C to +85°C, which ensures high reliability and improved stability. Other features include 100µW drive level, 5pF shunt capacitance, 8pF load capacitance, fundamental mode of operation, and an extended temperature range option. ECS ECX-1247 SMD Crystals are available in a low-profile ceramic package with a 1.6mm x 1.2mm footprint.
