MF & MF2 CRYSTALS
6 x 3.5mm SMD, 4 pad and 2 pad
FEATURES
8MHz to 125MHz
Miniature size: 6.0mm x 3.5mm height
Tight tolerances available
High shock and vibration resistance
Ideal for PDAs, GPS, PCMCIA and hand-held equipment
OUTLINE & DIMENSIONS
MF
DESCRIPTION
Miniature surface mount MF crystals incorporate a ceramic substrate
and hermetically-sealed metal lid. The combination of compact size
and low mass with a high-specification crystal make MF crystals ideal
for high density applications as well as hand-held and
communications equipment.
