LFXTAL081620

Overview

The LFXTAL081620 is a quartz crystal resonator manufactured by IQD Frequency Products. It operates at a nominal frequency of 48 MHz with a load capacitance of 8 pF. The component utilizes a fundamental oscillation mode and features an equivalent series resistance (ESR) of 50 Ohms. It is housed in a compact 4-SMD, no-lead surface-mount package measuring 3.20 mm x 1.80 mm x 1.00 mm maximum height. Designed for general-purpose timing applications, it supports standard operating conditions within the specified temperature range.

Feature Summary

• Fundamental mode quartz crystal operation
• Compact 4-SMD surface-mount footprint
• Standard 8 pF load capacitance specification

Applications

• Microcontroller clock inputs
• Communication interface timing circuits
• General-purpose digital logic synchronization

Procurement Notes

Verify the specific frequency tolerance and temperature stability requirements against the official datasheet before procurement. Confirm that the 8 pF load capacitance matches the host circuit design to ensure accurate frequency performance. Ensure the selected variant aligns with the required operating temperature range and physical dimensions for the target PCB layout.

Selection Notes

Select this component when a 48 MHz fundamental frequency is required in a small SMD package. Consider the 50 Ohm ESR value for oscillator circuit compatibility. Evaluate the 8 pF load capacitance requirement against the MCU or oscillator IC specifications to prevent frequency drift. Compare physical dimensions against available board space constraints.

Part Context

This part belongs to the LFXTAL series of quartz crystals from IQD Frequency Products. It is distinct from other series such as LFSPXO (clock oscillators) and LFTCXO (temperature-compensated oscillators). The LFXTAL series represents passive resonator components requiring external oscillator circuitry, unlike active oscillator outputs.

Replacement Considerations

Cross-reference with other 48 MHz 4-SMD crystals having 8 pF load capacitance and similar ESR values. Verify pinout compatibility if substituting with different manufacturers' packages. Ensure replacement parts meet the same fundamental mode and temperature stability requirements.
