TOKEN LTC 455/450 Chip Ceramic Filters Chip Ceramic Filters for Communication Surface Mount Ceramic Filters for Communication (Murata CFUCG Compatible) Preview Token chip ceramic filters LTC455/450 U/W series for communication (Compatible to Murata CFUCG series) comprises small, high performance, thin (4.0/3.0mm) consisting of 4/6 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 6.0/7.5 x 11.5mm) and 4.0/3.0mm 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 450 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. Features - They are slim, at only 4.0mm max. thickness, and have a small mounting area enabling flexible PCB design. - Operating temperature range: -20°C to +80°C. - Can be reflow soldered and withstand washing. - The bandwidth ranges from D to G. - Mountable by automatic placers.
