HC49/U Crystal

 BC1 - 13.5 X 11.5 x 4.7mm

The HC49/U crystal is an AT-cut, thru hole type crystal, designed for use in computer peripheral applications. The HC49/U offers tolerance and stability from ±5ppm to ±100ppm and a temperature range to -40o to +85oC.  The HC49/U is available with an optional gullwing design and mounting clip for SMD applications.  Available in fundamental, 3rd overtone, 5th overtone, or 7th overtone.



Features

  • Very compact and thin (13.5 x 11.5 x 4.7mm)
  • Frequency range from 2MHz to 220MHz
  • Perfect for mobile communications, computer peripherals and radio applications
  • High precision and high reliability
  • All Products meet the European Union Initiative (RoHS) for lead (Pb) free content and requirements for re-flow profiling using lead-free solder.
