LFXTAL003115B

Overview

The LFXTAL003115B is a parallel fundamental quartz crystal manufactured by IQD Frequency Products. It operates at a nominal frequency of 4.9152 MHz with a frequency tolerance of ±30 ppm and stability of ±50 ppm. The component utilizes a through-hole HC-49/3.5H package measuring 11.35 x 4.85 mm. It features a load capacitance of 30 pF and functions within a temperature range of -20°C to +70°C.

Feature Summary

• Hermetically sealed in an inert atmosphere with glass-to-metal seals on leads for durability
• Standard industry leaded package design compatible with traditional mounting methods
• Fundamental parallel resonance mode operation for precise timing applications

Applications

• General-purpose electronic timing circuits
• Microcontroller clock sources
• Consumer electronics requiring stable frequency references

Procurement Notes

Verify the specific packaging configuration, as bulk or cut tape options may exist. Confirm RoHS compliance status for environmental regulations. Ensure the driving level specifications align with the target circuit design to prevent over-driving the crystal. Validate that the load capacitance matches the oscillator circuit requirements for accurate frequency performance.

Selection Notes

Select this component when a standard through-hole crystal is required for 4.9152 MHz applications. Consider the HC-49 package size constraints and thermal operating limits. Compare against surface-mount alternatives if space is limited. Verify compatibility with the host oscillator's load capacitance and drive level settings.

Part Context

This part belongs to IQD’s extensive portfolio of quartz crystals, which includes SMD and THT options ranging from 1.2 x 1.0mm packages up to larger through-hole forms. The brand provides solutions for IoT, RFID, and general frequency control needs across various industrial and consumer sectors.

Replacement Considerations

Direct substitutes include other HC-49/3.5H crystals with identical 4.9152 MHz frequency, 30 pF load capacitance, and similar tolerance ratings. Cross-reference with other manufacturers offering hermetically sealed parallel fundamental crystals in the same physical footprint.
