Ceramic Filters for Radio Cassette Recorder (LTA)
Preview
ceramic filters for radio-cassette recorder LTA series are designed to address the needs of standard radio cassette
recorder requirements.
Recommend for use in low cost products where economically, efficient designs are critical. The nominal
frequency tolerance is ±2KHz.
Token LTA series ceramic filters conform to the RoHS directive.
Ceramic filters for radio cassette recorder LT 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.
