ECX-16 SMD Tuning Fork Crystals

ECS ECX-16 SMD Tuning Fork Crystals are miniature surface mount tunings fork crystals operating at 32.768kHz frequency. These tuning fork crystals exhibit ±20ppm frequency tolerance resulting in high reliability and improved stability. The ECX-16 tuning fork crystals offer low Equivalent Series Resistance (ESR) and an extended temperature range useful for low-power Real-Time Clock (RTC) applications such as STM32 AN2867. These tuning fork crystals feature a 1.6mm x 1.0mm compact footprint, 12.5ρF load capacitance, 0.5µW driver level, and are RoHS compliant. ECS ECX-16 SMD Tuning Fork Crystals are ideal for automotive, industrial, Commercial off-the-shelf (COTS) products, and the Internet of Things (IoT).
