It operates at a nominal frequency of 16 MHz with a load capacitance of 8 pF and an equivalent series resistance of 80 Ohms. The component features a frequency tolerance of ±20 ppm and stability of ±50 ppm across the operating temperature range of -40°C to +125°C. It utilizes a ceramic seam seal package measuring 3.2 x 2.5 x 0.8 mm in a 4-SMD, no-lead configuration. The device is AEC-Q200 qualified for automotive applications.

Crystals Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• Ceramic seam seal construction for environmental protection
• Wide operating temperature range suitable for harsh environments

Crystals Applications

• Automotive electronic control units
• Motor control systems
• DSP controller clock sources

Crystals Procurement Notes

Verify the specific load capacitance requirement of 8 pF against the target circuit design, as this differs from common 12 pF standard values. Confirm that the PCB footprint matches the 3.2 x 2.5 mm SMD package dimensions. Ensure the assembly process supports the specified maximum seated height of 0.8 mm to avoid mechanical interference with adjacent components.

Crystals Selection Notes

Select this component when a 16 MHz fundamental mode crystal is required for automotive-grade applications. The 8 pF load capacitance necessitates careful matching with the oscillator circuit's stray capacitance. Consider the 80 Ohm ESR when evaluating drive level sensitivity, ensuring the application does not exceed the 100 µW limit to maintain long-term frequency stability.

Crystals Part Context

This part belongs to the ECX-33Q series of ceramic seam seal crystals from ECS Inc. These components are designed for high-reliability surface-mount applications where small form factors and robust environmental sealing are critical. The series supports various frequencies and load capacitances tailored for industrial and automotive timing requirements.

Crystals Replacement Considerations

Direct substitutes include parts with identical 16 MHz frequency, 8 pF load capacitance, and 3.2x2.5mm package dimensions. Verify that any replacement also holds AEC-Q200 qualification if automotive compliance is mandatory. Cross-reference pinout compatibility for the 4-SMD no-lead configuration.
