MMD Components (Monitor & Quartztek) has taken its smallest quartz crystal to production. Measuring only 2 x 2.5 millimeters, with an ultra-low 0.57-millimeter profile, MMD’s new X series is a surface-mountable crystal that can be used in any application where space is limited and a frequency reference required, such as Bluetooth devices, PDAs, cell phones and MP3 players.

X series crystals are available with a wide frequency range of 16 to 60 MHz and a frequency tolerance/stability rate as high as ±50 ppm/±100 ppm. The units are fully RoHS compliant and compatible with Pb-free reflow profiles; feature ruggedized construction for extreme vibration and shock applications, allowing fundamental-mode operation to 60 MHz. And can operate in temperatures as high as 70 ºC.

Hermetically sealed in a 4-pad ceramic package, the crystals are delivered on tape and reel for easy pick and place. Availability for the new X series quartz crystals is stock to 8 weeks, with prices starting at $1.15 in quantities of 1000.
