LFXTAL026382BULK

Overview

The LFXTAL026382BULK is a quartz crystal oscillator manufactured by IQD Frequency Products, designed for surface-mount applications. It operates at a fundamental frequency of 11.0592 MHz with a frequency tolerance of ±30ppm and stability of ±50ppm. The component features a load capacitance of 16pF and an equivalent series resistance (ESR) of 60 Ohms. It utilizes a 4-SMD, no-lead package measuring 7.00mm in length, 5.00mm in width, and 1.40mm in maximum height. The device supports base harmonic operation within an operating temperature range of -20°C to +70°C.

Feature Summary

• Hermetically sealed construction using glass-to-metal seals on leads within an inert atmosphere
• Resistance welded termination style ensuring reliable electrical connections
• Surface-mount compatible 4-SMD no-lead package design for automated assembly

Applications

• Microcontroller clock generation circuits
• Communication interface timing references
• Industrial control system oscillators

Procurement Notes

Verify the specific suffix 'BULK' indicates standard bulk packaging rather than tape-and-reel configuration when reviewing distributor listings. Confirm that the 11.0592 MHz frequency matches the target circuit requirements exactly, as alternative frequencies are not interchangeable. Ensure the 16pF load capacitance aligns with the host oscillator circuit's external capacitor values to maintain specified accuracy. Check for any RoHS compliance markings if environmental regulations apply to the final product assembly process.

Selection Notes

Select this component when a precise 11.0592 MHz reference is required for UART baud rate generation or similar timing applications. The 4-SMD package offers a compact footprint suitable for space-constrained PCB layouts compared to through-hole alternatives. Consider the ±30ppm tolerance if high precision is needed; otherwise, wider tolerance options may be available. Evaluate the 60 Ohm ESR against the oscillator circuit's drive level limitations to prevent over-driving the crystal. The -20°C to +70°C range suits general commercial environments but may require extended temperature variants for harsher conditions.

Part Context

This part belongs to the 12SMX-B series from IQD Frequency Products, focusing on standard surface-mount quartz crystals. It complements other SMD offerings like the CFPX-104 series while providing specific frequency characteristics distinct from radial HC-49 packages. The manufacturer provides a broad portfolio ranging from 1.2x1.0mm packages to larger forms, catering to diverse industrial and consumer electronics needs across Europe and global markets.

Replacement Considerations

Direct substitutes must match the 11.0592 MHz frequency, 16pF load capacitance, and 4-SMD no-lead package dimensions. Cross-reference ESR values near 60 Ohms to ensure circuit compatibility. Verify that alternative manufacturers offer comparable ±30ppm tolerance and -20°C to +70°C operating ranges. Ensure the replacement maintains hermetic sealing standards if reliability in humid environments is critical.
