Additional Details

Ceramic resonators like the SPC7.3223K100K35TR12 are manufactured using piezoelectric ceramic materials. They offer a good balance of cost, size, and performance for many applications where high accuracy and stability are not critical requirements. The 'TR12' likely refers to the packaging type, indicating tape and reel for automated assembly processes. This resonator is commonly used in applications where a low-frequency clock signal is required, such as wake-up timers or basic timing functions in low-power devices. The specific load capacitance required for optimal performance should be checked in the datasheet. It's also important to consider the aging characteristics of ceramic resonators when designing long-life applications.
