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.
