ECX-12R Low ESR SMD Tuning Fork Crystals

ECS ECX-12R Low ESR SMD Tuning Fork Crystals are very compact ultra-miniature tuning fork crystals. The components are offered in a 2.0mm x 1.2mm x 0.6mm ceramic package with a frequency range of 32.768KHz. The ECX-12R crystals feature a 1.3pF shunt capacitance, an operating temperature range of -40°C to +85°C, and a 12.5pF load capacitance. ECS ECX-12R Low ESR SMD Tuning Fork Crystals are ideal for Internet of Things (IoT) applications and wearable technology.
