Compatible with Murata Resonators (ZTT)

Compatible with Murata Resonators (ZTT)

Direct ceramic resonator with built-in capacitor (ZTT) is compatible to Murata resonator CST series. Direct resonators provide an attractive alternative to quartz crystals for oscillation frequency stabilization in many applications. when compared to quartz devices, ceramics' easily mass production, low cost, mechanical ruggedness, and small size often outweigh the reduced precision to which frequencies can be controlled.

Additionally, (ZTT) resonators are better equipped to handle fluctuations in external circuit or power supply voltage due to their use of mechanical resonance and providing stable oscillation without adjustment. Further, these characteristics offer for a much faster rise times and are independent of drive level considerations.

Direct resonator (ZTT) series is used as standard clocks for microprocessors in various electronic devices. Direct produces miniaturized, high-performance (ZTT) resonator series using its superior fabrication, assembly and packaging technologies. The ZTT device offers frequency range from 1.79 MHz to 60.00 MHz with an initial frequency tolerance of ± 0.5%, stability tolerance ± 0.3% at -20°C ~ +80°C, and aging tolerance ± 0.3%. The ZTT resonator features built-in capacitance with 3 lead terminals to eliminates any need for external loading capacitors and reduces component count. These devices conform to the RoHS directive.

Application of specific designs also available including tighter tolerances and frequency adjusted to requirements. Contact Direct sales for more information. Download complete datasheet Ceramic Resonator Built-in Load Capacitance (ZTT) PDF (380KB).
