The CPPLC7LT-BR series from Cardinal Components, Inc., is a line of 3.3V CMOS oscillators designed for surface-mount technology (SMD) applications. These oscillators are commonly used in precision timing requirements, such as in microcontroller clocking, communication interfaces, and other digital circuits that need stable and accurate timing.

If you're working on embedded systems or digital designs that require a reliable clock signal, these oscillators are a solid choice. They operate over a wide temperature range, making them suitable for various environments. One thing worth noting is their low power consumption, which is beneficial in battery-powered devices. Engineers tend to reach for this when they need a compact, precise, and efficient solution for generating stable clock signals in small form factor designs. The SMD packaging also simplifies board layout and assembly processes, reducing the overall size of the end product.
