Part Marking:
SxFFFFFPymdz
or
LSxFFFFzywwz
Legend:
S
= Model code for SM42, Z = SM25, 5 = SM30
x
= Capacitance load code from below
FFFFF
= Frequency coded
P or L
= Pletronics
ymd or yww = Date of Manufacture (year, month and day) or year, week week
All other marking is internal factory codes
Some frequency marking examples: 3.579545M = 03579, 14.31818M = 14318, 24.0M = 24000
Specifications such as frequency tolerance and operating temperature range, etc. are not identified
from the marking. External packaging labels and packing list will correctly identify the ordered
Pletronics part number.
