The CM8V-T1A is a 32.768kHz tuning-fork SMD quartz crystal from Micro Crystal in a tiny 2.0×1.2×0.6mm package. With a ±20ppm frequency tolerance (±10ppm option), a 70kΩ max ESR, and multiple load-capacitance options (CL 4.0/7.0/9.0/12.5pF) to match the host oscillator, over −40~+85°C, it serves as the clock source for an RTC/MCU low-speed external oscillator (LSE) — for wearables, IoT, and metering. Note: this is a bare crystal, a different category from our RV-xxxx RTC modules (which embed their own crystal).
