ZTT 16.00 MHz Ceramic Resonator

• ZTT 16.00 MHz Ceramic Resonator is a highly dependable, three-pin frequency control device designed to provide a stable clock signal for high-speed microcontrollers and embedded systems. Consequently, it eliminates the need for external load capacitors by integrating them directly into the package, which significantly streamlines your printed circuit board (PCB) design. Furthermore, this cost-effective component serves as an excellent alternative to bulkier quartz crystals in applications where absolute precision is less critical. Therefore, engineers routinely select this resonator to optimize space and reduce manufacturing costs in mass-produced digital electronics.

Key Features:

• Integrated Load Capacitors: The device features built-in 30pF capacitors, simplifying the oscillator circuit and saving valuable board space.
• Fast Start-Up Time: It achieves stable oscillation much faster than standard crystals, enabling quicker system boot times.
• Excellent Durability: The robust ceramic construction naturally withstands physical shock and vibration better than traditional quartz alternatives.
• Compact Radial Package: The low-profile, through-hole design allows you to easily mount the component on densely packed circuit boards.
• Cost-Effective Operation: Additionally, it provides reliable timing functionality at a fraction of the cost associated with high-precision quartz oscillators.
