The component exhibits a frequency tolerance of ±30 ppm and a frequency stability of 50 ppm. It features an equivalent series resistance (ESR) of 40 Ohms and supports a maximum drive level of 500 uW. Designed for industrial environments, it functions within a temperature range of -20°C to +70°C. The device utilizes the HC49/4HSMX package format with SMD/SMT termination style.

Feature Summary

• Provides precise timing reference at 11.0592 MHz using standard quartz resonance technology
• Engineered for surface mount assembly via the HC49/4HSMX footprint configuration
• Maintains stable oscillation performance across specified industrial temperature ranges

Applications

• Industrial control systems requiring stable clock signals
• Communication equipment utilizing serial data transmission protocols
• Microcontroller-based embedded systems needing precise timing references

Procurement Notes

Verify the specific package variant and reel quantity requirements against your manufacturing line capabilities before ordering. Confirm that the HC49/4HSMX form factor aligns with your PCB design constraints. Ensure the operating temperature range meets your environmental specifications. Cross-reference the manufacturer's latest datasheet for any recent packaging or material compliance updates to guarantee supply chain accuracy and regulatory adherence.

Selection Notes

Select this component when a 11.0592 MHz frequency is required for digital logic synchronization. The 20 pF load capacitance must match the oscillator circuit design parameters. Consider the 40 Ohm ESR value for impedance matching in the driving circuit. This part is suitable for applications where moderate frequency stability is sufficient and surface mount processing is preferred over through-hole alternatives.

Part Context

This crystal belongs to the general quartz resonator category from IQD Frequency Products. It serves as a passive frequency-determining element in electronic circuits. Unlike active oscillators, it requires an external circuit to generate a square wave signal. The HC49/4HSMX package represents a compact surface-mount version of traditional cylindrical crystals, offering space savings while maintaining robust mechanical characteristics.

Replacement Considerations

Direct substitutes include other 11.0592 MHz crystals with identical 20 pF load capacitance and compatible ESR values. Verify that alternative parts support the same HC49/4HSMX footprint and operate within the -20°C to +70°C range. Ensure the replacement maintains the ±30 ppm tolerance requirement for system timing integrity.
