Technical Report for Low Current Consumption Type Oscillators
SMD type oscillators had been used almost all type of application these days.
Market expansion required product downsizing, and various size of products has been developed and introduced to the market.
Downsized oscillators was successful to fit in mobile type applications like compact digital camera, notebook computer and PDA. 
Such application requires low power consumption concerning of battery life, so power consumption of each components becomes critical parameters these days.
Under such circumstance, KDK introduce low current consumption type oscillators to the market.
You can ask Low Current Consumption Option at MIN(7.5x5.0mm), DUT(5.0x3.5mm) and MEG(3.0x2.5mm) type.
