Product Description

Consisting of a piezoelectric resonator (wide band type), Ceramic Discriminator, is widely used for various mobile communications equipment. The compact size and light weight of the component makes it perfect for a wide range of applications that require downsizing including mobile phones. The discriminator is stable and highly sensitive owing to which it delivers superior performance while consuming little power. Furthermore, it can be combined with a number of other IC’s owing to which  its scope of applications increases significantly.
