Citizen introduce new model CM315E. Low motional resistance 50KΩ max. available (CM315EL series).
Advantages: 1) Pin #2 can be connected to ground. This can be minimized the noise problem and is suitable for noise sensitive application. 2) Pin #1 and Pin #3 on one side. This enable to design high density circuit and space problem can be solved. Also high flexibility of circuit design.
