Crystals Procurement Notes

Verify the specific manufacturer datasheet for absolute maximum ratings and soldering profiles before integration. Confirm that the 4-pin footprint matches the PCB layout, as pin assignments may vary between manufacturers. Ensure the load capacitance requirements of the host oscillator circuit align with the component's 20 pF specification to maintain accurate frequency performance.

Crystals Selection Notes

Select this component when a 12 MHz reference is required for low-power or cost-sensitive applications. The 100 Ohm ESR value must be compatible with the driving circuit's impedance. Consider the ±10 ppm stability requirement against environmental temperature variations, noting the specified operating range extends from -20°C to +70°C for standard commercial use cases.

Crystals Part Context

This crystal is commonly integrated into open-source microcontroller boards such as the MITAYI Pico RP2040. It serves as the primary clock source for the processor, replacing older 2-pin configurations with a more robust 4-pin design to improve mechanical stability and electrical performance in modern embedded hardware implementations.

Crystals Replacement Considerations

Direct substitutes include other 12 MHz 4-pin SMD crystals with identical 20 pF load capacitance and similar ESR values. Verify physical dimensions of 3.2 x 2.5 mm to ensure compatibility with existing footprints. Cross-reference frequency tolerance and operating temperature ranges to maintain system reliability.
