Crystals Procurement Notes

Verify the specific load capacitance requirement against your circuit design, as this unit specifies 12 pF. Confirm that the ±25 ppm frequency tolerance meets your system's accuracy needs. Ensure the operating temperature range of -40°C to +85°C aligns with your environmental conditions. Check for any specific mounting or reflow soldering profile requirements provided in the official datasheet to ensure reliable assembly.

Crystals Selection Notes

Select this component when a 12 MHz fundamental frequency is required in a small form factor. The 12 pF load capacitance must match the oscillator circuit specifications. Consider the ±25 ppm tolerance if higher precision is not critical. The 4-SMD package is suitable for automated surface mount assembly processes requiring low profile components.

Crystals Part Context

This part belongs to the ECX-32 series of crystals, characterized by its 3.2mm x 2.5mm footprint. It is designed for applications where space constraints are significant but standard crystal performance is sufficient. The series offers various frequency and tolerance options within the same physical package.

Crystals Replacement Considerations

Direct substitutes may include other 12 MHz crystals with identical 12 pF load capacitance and similar ±25 ppm tolerance in a 4-SMD no lead package. Verify pin compatibility and electrical parameters before substitution.
