ECX-33Q SMD Quartz Crystals

ECS ECX-33Q SMD Quartz Crystals are miniature SMD crystals with a 3.2mm x 5.5mm footprint. These crystals meet AEC-Q2000 qualification requirements and are RoHS compliant. The crystals offer a frequency range of 12MHz to 40MHz with ±10ppm to ±30ppm tolerance and ±30ppm, ±50ppm, or ±100ppm stability. These compact and low-profile crystals are available in tape-and-reel packaging. ECS ECX-33Q SMD Quartz Crystals feature a gold (Au) lead finish and moisture sensitivity level (MSL) 1.
