High-Selectivity Ceramic Filter
for TV/VCR Stage Compatible Murata SFT
Preview
Token high-selectivity Ceramic filters for TV/VCR stage LTT MA series is 4 element devices that offer more
selectivity than the conventional LT series (Murata SFE). The improved spurious suppression of these filters
eliminates the need for cascading multiple filtering devices; therefore, it is possible to design a more compact
circuit board configuration.
Token High-Selectivity Filter LTT MA series conform to the RoHS directive. This high-selectivity device can be
customed designs and tighter tolerances available on request.
Application of ceramic filter 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 (15±2.0 x 7.5±2.0 x 3.0±1.0 mm), Insert Loss max 9db and 10dB, Spurious Attenuation min
40dB and 50 db, and Input/Output Impedance 470Ω, 600Ω, 1000Ω, Nominal Center Frequency (fo) (MHz) of
LTT MA series is available 4.500MHz, 4.724MHz, 5.500MHz, 5.742MHz, 6.000MHz, 6.250MHz, 6.500MHz,
and 6.742MHz.
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.
