STD-CTZ-1-19.2M

Overview

The NDK STD-CTZ-1-19.2M is a surface-mount crystal unit with a nominal frequency of 19.2 MHz and a frequency tolerance of ±10 ppm. It features a 4-SMD, no-lead package measuring 2.0 mm by 1.6 mm with a maximum height of 0.65 mm. The device has a load capacitance of 7 pF and an equivalent series resistance (ESR) of 80 Ohms. It operates within a temperature range of -30°C to +85°C and includes a built-in NTC thermistor for precise temperature compensation.

Feature Summary

• Integrates a high-precision NTC thermistor directly within the hermetic cavity adjacent to the crystal element for accurate thermal monitoring.
• Provides enhanced frequency stability across wide temperature variations through integrated thermal sensing capabilities.
• Utilizes a compact 2016 surface-mount package designed to minimize PCB footprint while maintaining standard reflow soldering compatibility.

Applications

• Mobile communication modules requiring precise clock synchronization
• GNSS receivers needing high-frequency accuracy for positioning
• Wearable electronic devices with strict space constraints
• Ultra-thin consumer electronics utilizing multimedia processors

Procurement Notes

Verify that the specific part number corresponds to the NX2016SF series variant containing the integrated NTC sensor. Confirm the required load capacitance matches the system design, as standard versions typically specify 7 pF. Ensure the application environment falls within the specified operating temperature range of -30°C to +85°C to guarantee performance specifications are met.

Selection Notes

Select this component when both tight frequency tolerance and precise on-chip temperature measurement are required in a minimal footprint. It eliminates the need for external NTC components, simplifying layout and improving compensation accuracy compared to discrete solutions. Suitable for designs where PCB area is limited and thermal drift correction is critical for signal integrity.

Part Context

This component belongs to NDK's line of crystal units with built-in temperature sensors, specifically the NX2016SF series. These devices address the limitations of separate crystal and thermistor arrangements by integrating both functions into a single hermetically sealed package. This integration ensures the sensor measures the actual crystal temperature rather than ambient board conditions.

Replacement Considerations

Direct substitutes include other models from the NX2016SF series with different frequencies, such as NX2016SF-26M or NX2016SF-38.4M. Cross-brand replacements must match the 2016 package dimensions, 7 pF load capacitance, and integrated sensor functionality to maintain design parameters.
