SMD Ceramic Resonators MHz (ZTAC/ZTTC)
Direct (ZTAC/ZTTC) series is the smallest surface mount ceramic resonators (Murata resonator CSAC/CSTC compatible). Previously, only higher cost quartz crystal resonators were considered for CAN bus application, due to tighter frequency tolerance requirements than for traditional automotive bus applications. Nowaday, Direct utilizes the latest ceramic piezo technology freeing the design engineers from having to use these higher cost components and still achieve desired reliability and performance targets.
Direct ZTAC and ZTTC series are the SMD ceramic resonators that meet the frequency tolerance ±0.5%, temperature tolerance ±0.3% ~ ±0.4%, and aging tolerance ±0.3%. The ZTAC and ZTTC covers the frequency range of 1.79 MHz to 50.00 MHz. ZTTC series features a built-in load capacitance. This feature eliminates any need for external loading capacitors and reduces component count, increases reliability and reduces size.
The ZTACE×MG (3.2 x 1.3 mm) with (max) profile 1.0 mm and ZTACW×MX (2.5 x 2.0 mm) with (max) profile 1.5 mm are the smallest resonators for their respective frequency ranges. All ZTAC and ZTTC series are surface mount devices (SMD) with operating temperature range is -20°C to +80°C.
Tolerance is the main key characteristics to evaluate for a resonator. The total tolerance is the addition of the initial tolerance, temperature tolerance and aging tolerance. Tighter tolerances are possible through design advancements, material refinement and manufacturing techniques. Direct's design and material improve the temperature and aging characteristics of the resonator. Direct's manufacturing ability sort to tighter initial tolerances.
Custom parts are available on request. Direct will also produce devices outside these specifications to meet specific customer requirements, please contact Direct sales for more information.
