LFXTAL056855

Overview

The LFXTAL056855 is a fundamental mode quartz crystal manufactured by IQD Frequency Products, designed for surface-mount applications. It operates at a nominal frequency of 13 MHz with a frequency tolerance of ±30ppm and stability of ±50ppm. The component features an 18pF load capacitance and an equivalent series resistance (ESR) of 40 Ohms. It is housed in a 4-SMD, no-lead package measuring 5.00mm x 3.20mm with a maximum height of 1.00mm. The device supports a wide operating temperature range from -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Fundamental oscillation mode ensures stable frequency generation for clock circuits.
• Surface-mount 4-SMD package facilitates automated PCB assembly processes.
• Wide operating temperature range supports reliable performance in varied environmental conditions.

Applications

• Microcontroller clock sources
• Communication interface timing
• General-purpose digital circuit oscillators

Procurement Notes

Verify the specific package variant upon ordering, as distributor listings may reference HC49/4HSMX formats which differ from the standard SMD footprint. Confirm that the selected reel or cut tape quantity aligns with production requirements. Ensure the supplier provides valid RoHS3 compliance documentation. Cross-reference the manufacturer part number directly with IQD Frequency Products official catalogs to avoid substitution errors during procurement.

Selection Notes

Select this component when a 13 MHz fundamental frequency is required for surface-mount designs. The 18pF load capacitance must match the oscillator circuit design specifications. Consider the ±30ppm tolerance for precision timing needs. Evaluate the 40 Ohm ESR against the driving level constraints of the host microcontroller or logic gate. Ensure the -40°C to +85°C temperature range meets the application's operational environment.

Part Context

This crystal belongs to the general quartz crystal category within IQD Frequency Products' portfolio. It serves as a passive frequency control element distinct from active oscillators. The 4-SMD form factor represents a compact solution compared to through-hole alternatives like HC49S, allowing for higher density PCB layouts in modern consumer and industrial electronics.

Replacement Considerations

Direct substitutes must match the 13 MHz frequency, 18pF load capacitance, and 4-SMD 5.00x3.20mm dimensions. Verify equivalent ESR and tolerance ratings. Check if alternative manufacturers offer compatible pin-out and thermal characteristics. Ensure any replacement maintains the same fundamental mode operation and temperature range specifications.
