ECS ECX-32 Compact SMD Ceramic Crystals

ECS ECX-32 Compact SMD Ceramic Crystals are subminiature SMD crystals in a 3.2mm x 2.5mm x 0.8mm package with an 8MHz to 54MHz frequency range. The ECX-32 components offer a frequency tolerance of ±50ppm at +25°C and frequency stability of ±50ppm in a -20°C to +70°C temperature range. An extended temperature range option is available( as low as -55°C up to +125°C). These crystals are ideal for SMD manufacturing environments with automated assemblies. Typical applications include LoRa WAN, wireless, and high density.
