  • KHz AM Ceramic Filters (LTP) Murata Filter SFU450/455kHz Compatible

Token ceramic filters are primarily designed for piezoelectric lines and conform to the RoHS directive and Lead-free. Ceramic (LTP) filters for AM 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 (LTP) 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 filters specific designs also available including different piezo band-pass devices and Q specifications adjusted to frequency requirements.
