SMT Crystals Are For Automatic Placement

Designed for use with automatic pick-and-place machines, SM-Q series crystal oscillators come with dimensions of 7 x 5 x 1.1 mm on a ceramic substrate with seam welded lid. Fundamental frequency range is 9.5 to 33 MHz, third overtones from 33 to 85 MHz, frequency tolerance options are ±10, ±30 or ±50 ppm at 25°C and frequency stability options of ±5 or ±10 ppm over 0°C to 50°C or ±25 or ±50 ppm over -10°C to 60°C. Equivalent series resistance is 40 ohms maximum for fundamental frequency and 80 ohms maximum for third overtone.
