SMD EC Models, TCXOs, 3.0 Volts
MF Electronics EC (SMD) TCXOs are ideal for high volume,
low cost applications. With miniature 9 x 7 x 2 mm size,
these oscillators use tiny precise crystals operating at stan-
dard frequencies from 12.6 to 19.68 MHz. Seven common
frequencies are available. These oscillators have electronic
frequency control of ±7 ppm, allowing the frequency to be
set to, or to track a reference frequency.
Operating at 3.0 volts and with current not exceeding 1.5,
mA, they are ideal for battery operated equipment.
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.
