6 x 3.5mm SMD, 4 pad or 2 pad
DESCRIPTION
Miniature surface mount MF crystals incorporate a ceramic substrate
and hermetically-sealed metal lid. The 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.
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
