LFXTAL003200BULK

Overview

The LFXTAL003200BULK is a parallel fundamental quartz crystal manufactured by IQD Frequency Products. It operates at a nominal frequency of 14.31818 MHz with a frequency tolerance of ±30 ppm and stability of ±50 ppm. The component utilizes an HC-49/4H surface mount package, measuring 11.05 mm in length and 4.65 mm in width. Key electrical parameters include a load capacitance of 30 pF, a maximum shunt capacitance of 7 pF, and a maximum equivalent series resistance (ESR) of 130 Ω. The drive level is limited to 500 µW. It supports a standard operating temperature range from -20 °C to +70 °C.

Feature Summary

• Hermetically sealed construction using glass-to-metal seals within an inert atmosphere for long-term reliability.
• Resistance-welded lead wires mounted on a plastic former to create a stable gull-wing surface mount configuration.
• Fundamental parallel resonance mode operation optimized for standard oscillator circuits.

Applications

• General-purpose digital clock signal generation
• Microcontroller system timing references
• Industrial control equipment oscillators

Procurement Notes

Verify the specific lot code and RoHS compliance status directly with the manufacturer or authorized distributor prior to ordering. Confirm that the HC-49/4H package dimensions align with the target PCB footprint. Ensure the driving circuit design respects the 500 µW maximum drive level to prevent frequency shifts or crystal damage. Validate that the ±50 ppm stability meets the system requirements across the full -20 °C to +70 °C operating temperature range.

Selection Notes

Select this component when a 14.31818 MHz reference is required in a robust surface mount package. The HC-49/4H form factor offers a balance between mechanical durability and board space efficiency compared to through-hole alternatives. Consider the 30 pF load capacitance requirement to ensure proper oscillator loop matching. This model is suitable for applications where moderate frequency stability is sufficient and hermetic sealing provides necessary environmental protection.

Part Context

This part belongs to the LFXTAL series of industrial-grade quartz crystals from IQD Frequency Products. It represents a standard industry-compatible SMD variant designed for high-volume manufacturing. The HC-49/4H package is widely recognized in consumer and industrial electronics for its reliable performance and ease of automated assembly. It serves as a foundational timing element for various digital logic families.

Replacement Considerations

Cross-reference with other HC-49/4H format crystals offering 14.31818 MHz frequency and 30 pF load capacitance. Verify that substitute parts match the 130 Ω ESR limit and 500 µW drive level specifications. Ensure replacement components maintain the same -20 °C to +70 °C temperature range and hermetic seal construction for equivalent reliability.
