Marking Explanation
Example: 32K152B
The 32K is a code indicating frequency, in this case
32.768kHz
The 152 is the date code in YWW, ie.2001 wk 52
The letter on the end indictes: A for 90SMX, B for 91SMX
Note, if the letter is at the end of the crystal then it is
12.5pF loaded. If it apears after the 32K as 32KA152, then
the crystal is 6pF loaded. This is the same for both 90SMX
and 91SMX.
For typical soldering conditions, please see the relevant
Please contact our sales office for current leadtimes
90SMX & 91SMX surface mount crystals are plastic
encapsulated
Load Capacitance (C
Drive Level: 1.0µW max
90SMX & 91SMX surface mount crystals are available
packaged individually or on tape and reel
