ECX-31B SMD Crystals

ECS ECX-31B SMD Crystals are ultra-miniature surface mount tuning fork crystals that operate at 32.768kHz frequency. These SMD tuning fork crystals exhibit ±20ppm frequency tolerance at +25°C which ensures improved reliability. ECS ECX-31B SMD Crystals feature a 1µW drive level, 70kΩ equivalent series resistance (ESR), and an extended temperature range. These tuning fork crystals have a compact design and come in a low-profile ceramic package, which makes them ideal for applications in SMD manufacturing environments.
