TOKEN LTZ Ceramic Filters for AM Ceramic Filters for AM The Low Cost Standard AM Filters (Murata SFZ Compatible) Preview Ceramic filters for AM (LTZ) series are designed to address the needs of standard AM filtering requirements and are recommended for use in low cost products where economically, efficient designs are critical. Token ceramic filters LTZ series for AM conform to the RoHS directive. The LTZ series can be customed designs and tighter tolerances available on request. Application of ceramic filters specific designs also available including different piezo band-pass devices and Q specifications adjusted to frequency requirements. Token ceramic filters can supply you high performance, high quality and stability. With dimensions (7.0 x 9.0 x 6.5mm), and Insertion Loss 7db, the (LTZ) series is composition of 2 elements direct coupling. Center Frequency (fo) is available in a range of 450kHz ~ 470kHz. The nominal frequency tolerance is ±2kHz. 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.
