HC45/U Crystal

8.40 X 7.90 X 3.20mm

The HC45/U Crystal is a miniature AT-Cut thru hole type crystal, designed for use in applications where space is limited. The HC45/U offers tolerance and stability to ±5ppm and a temperature range to -40o to +85oC.  The HC45/U is available with an optional gullwing design and mounting clip for SMD applications.  Available in Fundamental or 3rd overtone.

Features

  • Very compact and thin (8.40 X 7.90 X 3.20mm)
  • Frequency range from 4 MHz to 200 MHz
  • Perfect for Mobile Communication 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.
