PART NUMBER GENERATION

Part numbers for X32 crystals are generated as follows:

16.000MHz X32/10/10/-10+60/12pF/80R

X32 CRYSTALS

3.2 x 2.5 x 0.7mm SMD

12.0MHz to 60MHz

Example:

value is required)

DESCRIPTION

MT crystals are ultra-miniature AT-cut crystals covering the frequency

range 12MHz to 60MHz in fundamental mode. Their small size and low

mass makes these crystals ideal for miniaturized hand-held equipment

and similar high-density applications.

Frequency range 12MHz to 60MHz, fundamental mode

Ultra-small package 3.2mm x 2.5mm x 0.6mm

Entire package may be grounded via metal lid and two pads

Packaged in standard EIA tape and reel

Extremely low ageing with high shock and vibration resistance

Ideal for PDAs, hand-held GPS, PCMCIA etc.
