SMD Tuning Fork Crystal 7.0*1.5

The Epson MC-146 series, which is a type of low-profile SMD (Surface Mount Device) crystal unit designed for various electronic applications. These crystal units typically operate in the kHz frequency range.These crystal units are designed with a low profile, making them suitable for applications with space constraints or where a compact design is desired. Crystal units like the MC-146 series can be used in a wide range of applications, including real-time clocks (RTCs), microcontrollers, communication devices, sensor networks, and more.
It's important to consider the appropriate load capacitance when using the MC-146 series for proper oscillation.
