Ceramic Discriminators 455kHz (JTM)

Ceramic discriminator for communication (JTM) is compatible to Murata CDB/CDBC/CDBM. (JTM) For Communication consists of wide band piezoelectric resonator. It is ideal for mobile communication equipment due to its small size and light weight. Standard line includes products for a wide range of applications, from cordless telephones to cellular telephones, making non-adjustment and shrinking of the detection circuit possible.

Direct (JTM) including features with small in size and lightweight, realize non-adjustment in detection circuit, high sensitivity and stability, wide range of standard products are available for various ICs, operating temperature range: -20°C to +80°C and storage temperature range: -40°C to +85°C.
