The (LTC455/450 U/W) series for communication filter comprises small, high performance, thin (4.0mm) consisting of 4 ceramic elements. Their innovative construction is perfect for shrinking mobile communication products such as pocket pagers and cellular phones.

The surface mount LTC455/450 U/W series for AM use is one of the most recommendable intermediate filters, having such distinctive features as high selectivity, high stability and adjustment-free operation. Additionally its easy matching with IC helps create an easy circuit design.

With dimensions (7.5 x 6.0 mm) and 4.0 mm low profile, the LTC455/450 U/W filters have a small mounting area enabling flexible PCB design and are suitable for automatic placers. Standard Center Frequency is 455kHz with tolerance ±1.5 and 450kHz is also available. Pass Band Ripple (dB) max is 2db, Input / Output Impedance is 1000Ω and 1500Ω.

Custom parts are available on request. Token will also produce devices outside these specifications to meet specific customer requirements, please contact our sales for more information.
