SMD EB Models, TCXOs, 3.0 Volts
MF Electronics EB (SMD) TCXOs are ideal for high volume,
low cost applications. With miniature 7 x 5 x 2 mm size,
these oscillators use tiny precise crystals operating at stan-
dard frequencies from 10 to 20 MHz. Thirteen common fre-
quencies are available. They have electronic frequency con-
trol of ±5ppm, allowing the frequency to be set to, or to
track a reference frequency.
Operating at 3.0 volts and with current not exceeding 2
mA, they are ideal for battery operated equipment. This
group of models include the 10 MHz and 20 MHz frequen-
cies which may be used for counting and timing applica-
tions.
They are furnished in tape and reel, for automated produc-
tion and come with large gold or solder plated pads. Side-
castellations accept solder flow, and facilitate automated
solder joint inspection.

NOTES
(1) Number in date code is year. In example, “1” is 2001.
(2) Letter in date code is one two-week period. Year is divided
into 26 two-week intervals. Each two-week interval is repre-
sented by one letter of the alphabet, in sequence.
