Size: A minimum-size crystal clock oscillator with dimensions of 2.5 ꢀ 2.0 mm.
Thickness: Ultra-thin with a thickness of 0.9 mm.
Pb
Weight: Weighs only 0.02 g, giving unparalleled light-weight.
This crystal clock oscillator can support low frequencies (from ꢁ.5 MHz); an
achievement not easy for other crystal oscillators of the same size to equal.
Automatic mounting by taping and IR reflow (lead-free) are possible.
