Token resonators KHz (ZTB) series is designed to provide the 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 nominal ±2%~±3% requirements of one chip microprocessors. Stability and aging tolerance are tight to ± 0.3%.
Features:
- Oscillating circuits requiring no adjustment can be designed by utilizing these resonators in conjunction with transistors or appropriate ICs
- The ZTB series is stable over a wide temperature range and with respect to long-term aging
- Miniature and lightweight, standardized for use in low profile devices
- Highly reliable design with excellent environmental resistance
- The ZTB series comprises fixed, tuned, solid-state devices
- Operation Temperature (-20°C~+80°C)
- Low cost
Applications:
- Square-wave and sine-wave oscillators
- Clock generator for microprocessors
- Remote control systems
