ZTB (kHz) Series is designed to provide the design engineer with a rugged, relatively low
frequency device in the frequency range of 190 kHz to 1,250 kHz. Initial frequency tolerance is ± 0.5 % which compares
very favorably to the norminal ± 2% ~ ± 3% requirements of one chip microprocessors. Token ZTB series utilizes the area
vibration mode of the piezoelectric element.| ZTB (kHz) Compatible to Murata CSB | 190 - 1250 kHz |
