TOKEN LTP Ceramic Filters for AM Ceramic Filters for AM Token Ceramic Filters for AM are Compatible Murata SFU450/455kHz Preview Token ceramic filters are primarily designed for piezoelectric lines and conform to the RoHS directive and Lead-free. Ceramic filters for AM (LTP) series are designed to address the needs of standard AM filtering requirements. These filters are recommended for use in low cost products where economically, efficient designs are critical. The LTP 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. Token ceramic filters can supply you high performance, high quality and stability. The LTP 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. Benefit Features - Center frequency range between 450~470kHz are available standard tolerance of ±2kHz. - Insert Loss (dB) max 5.0 db.
