FEATURES

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

MF & MF2 CRYSTALS

6 x 3.5mm SMD, 4 pad or 2 pad

OUTLINE & DIMENSIONS

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.
