Features
l
Size: A minimum-size crystal clock oscillator with dimensions of 2.5 x 2.0 mm.
l
Thickness: Ultra-thin with a thickness of 0.9 mm.
l
Weight: Weighs only 0.02 g, giving unparalleled light-weight.
l
This crystal clock oscillator can support low frequencies (from 1.5 MHz); an
achievement not easy for other crystal oscillators of the same size to equal.
l
Automatic mounting by taping and IR reflow (lead-free) are possible.
l
Lead-free.
