X322516MLB4SI

Thanks to its high accuracy, stability, and reduced EMI features, this surface-mount crystal is ideal for a wide variety of modern electronic applications. It is frequently designed into Internet of Things (IoT) devices, smart wearables, and various wireless communication modules that require a precise clock reference.

To ensure proper circuit compatibility, your microcontroller or RF IC must support a 16MHz external clock source. Additionally, the PCB layout must be designed to match the SMD3225-4P footprint, and the external load capacitors ($C_1, C_2$) should be calculated appropriately based on the crystal's 9pF load capacitance and board stray capacitance.

If you need a drop-in replacement, look for crystals that match the SMD3225-4P package dimensions (3.2x2.5 mm) and the 16MHz nominal frequency. For critical timing applications, ensure that the replacement meets or exceeds the original's ±10ppm frequency tolerance, ±20ppm frequency stability, and 9pF load capacitance to avoid frequency shifting.

Yes. During PCB assembly, follow the recommended reflow soldering profile for SMD quartz crystals to avoid thermal shock. For optimal performance, place the crystal as close as possible to the IC pins, keep the clock traces short and symmetrical, and implement a solid ground plane underneath to minimize stray capacitance and electromagnetic interference (EMI).

The YXC Crystal Oscillators X322516MLB4SI is a 16MHz crystal featuring a 9pF load capacitance. It comes in a compact SMD3225-4P package (3.20x2.50x0.70 mm), offering a normal temperature frequency tolerance of ±10ppm, a frequency stability of ±20ppm, and an operating temperature range of -40℃ to +85℃.
