ECX-1247B SMD Crystals

ECS ECX-1247B SMD Crystals are compact and offer a 24MHz to 80MHz operating frequency range for wireless applications. The crystals feature ±25ppm frequency tolerance, ±10ppm frequency stability, 100µW drive level, and 5pF shunt capacitance. These SMD crystals operate at a temperature range from -40°C to +85°C and have a 1.6mm x 1.2mm footprint with a low 0.3mm profile. Applications for ECS ECX-1247B SMD Crystals include RFID, NFC, Wi-Fi®, RF, and video / audio.
