LFXTAL018153BULK

Overview

The LFXTAL018153BULK is a quartz crystal resonator from IQD Frequency Products, designed for precise timing applications. It operates at a nominal frequency of 4.9152 MHz with a frequency tolerance of 30 ppm and a load capacitance of 16 pF. The component utilizes an HC49/4HSMX surface-mount package, measuring approximately 7.2 mm in length, 5.2 mm in width, and 1.4 mm in height. It supports a supply voltage range typically associated with standard logic interfaces, though specific electrical parameters are defined by the crystal characteristics.

Feature Summary

• Hermetically sealed construction using resistance welding and glass-to-metal seals on leads within an inert atmosphere
• Surface mount design compatible with automated assembly processes
• Standard leaded package form factor adapted for SMD mounting

Applications

• General purpose clock generation circuits
• Microcontroller system timing references
• Communication interface synchronization

Procurement Notes

Verify the exact package variant (HC49/4HSMX) against schematic footprints, as dimensions may vary slightly between bulk and reel packaging types. Confirm that the 16 pF load capacitance matches the oscillator circuit requirements. Ensure the 30 ppm tolerance meets the system's frequency accuracy needs. Check RoHS compliance status if restricted substances are a concern. Validate the operating temperature range against environmental conditions.

Selection Notes

Select this component when a stable 4.9152 MHz reference is required in a compact surface-mount format. The HC49/4HSMX package offers a balance between performance and board space efficiency. Consider the 30 ppm tolerance for general digital systems where high precision is not critical. Evaluate the 16 pF load capacitance to ensure proper oscillation stability in the target circuit design.

Part Context

This part belongs to the LFXTAL series of quartz crystals from IQD Frequency Products. It is distinct from the CFPS-73 oscillator series and other LFSPXO models. The BULK suffix indicates the packaging method, which may affect handling and storage requirements compared to tape-and-reel variants. It serves as a passive frequency control element rather than an active oscillator.
