LFXTAL059531

Overview

LFXTAL059531 is a fundamental mode quartz crystal resonator manufactured by IQD Frequency Products. It operates at a nominal frequency of 24.576 MHz with a frequency tolerance of ±20 ppm. The component features an equivalent series resistance (ESR) of 40 Ohms and requires a load capacitance of 18 pF for proper circuit integration. It is housed in a compact 4-SMD, no-lead surface mount package with physical dimensions of 5.00 mm length, 3.20 mm width, and a maximum height of 1.00 mm. The device is designed for reliable performance across a standard operating temperature range.

Feature Summary

• Fundamental parallel resonance operation providing stable timing signals
• Surface mount construction utilizing a leadless SMD package design
• Hermetically sealed glass-to-metal structure ensuring environmental durability

Applications

• Digital clock signal generation in microcontroller systems
• Synchronization circuits in communication modules
• Timing references for data conversion interfaces

Procurement Notes

Verify the specific packaging configuration required for production, as bulk or tape-and-reel options may be available. Confirm that the 18 pF load capacitance matches the host circuit's oscillator design requirements. Ensure the 40 Ohm ESR specification is compatible with the driving circuitry to prevent overdriving the crystal element during assembly and operation.

Selection Notes

Select this component when a precise 24.576 MHz reference is needed in space-constrained designs. The 4-SMD footprint offers a smaller profile compared to traditional through-hole crystals. Consider the ±20 ppm initial tolerance against system timing budgets. Evaluate the 40 Ohm ESR to ensure adequate drive level margin within the oscillator circuit constraints.

Part Context

This part belongs to the standard quartz crystal family from IQD Frequency Products. It serves as a passive frequency-determining element rather than an active oscillator. Unlike MEMS oscillators such as the IQMS series, it requires an external oscillator circuit to generate a square wave output. It complements IQD's broader portfolio of TCXOs and VCXOs for applications requiring higher stability or tuning capabilities.

Replacement Considerations

Direct replacements must match the 24.576 MHz frequency, 18 pF load capacitance, and 40 Ohm ESR. Verify that substitute components utilize the same 4-SMD no-lead package dimensions to ensure PCB compatibility. Check if alternative manufacturers offer identical electrical parameters and hermetic sealing standards for equivalent reliability.
