TIGHT TOLERANCE THERMOPLASTIC ENCASED SMD CRYSTAL
FK
The FK is an AT-cut tight tolerance SMD crystal designed to
withstand extreme heat from IR reflow operations. This new
compact package is formed before the crystal is inserted which
allows for tighter tolerances and stabilities.
FEATURES
• Tight Tolerance and Stability
• Cost Effective
• Excellent Hermeticity
• Tape and Reel (1,000 pcs. STD)
