ILCX19-FF5F10-48.000MHZ

Crystals Overview

The ILCX19-FF5F10-48.000MHZ is a parallel fundamental quartz crystal from the ILSI ILCX19 series, designed for surface mount applications. It operates at a nominal frequency of 48 MHz with a load capacitance of 10 pF and an equivalent series resistance (ESR) of 80 ohms maximum. The component features a 4-pin SMD ceramic package measuring 2.0mm x 1.6mm x 0.55mm. It offers a frequency tolerance of ±30 ppm at 25°C and aging stability of 5 ppm per year. The device supports lead-free processing and is suitable for high-density circuit designs requiring precise timing.

Crystals Procurement Notes

Verify that the specific part number matches the required frequency and tolerance specifications before integration. Confirm that the PCB footprint aligns with the 2.0mm x 1.6mm dimensions to ensure proper solder joint formation. Ensure supply chain sources provide genuine components to maintain frequency stability and reliability standards in final assembly processes.

Crystals Selection Notes

Select this component when a low-profile surface mount crystal is required for space-constrained designs. The 10 pF load capacitance must match the oscillator circuit requirements to achieve the specified ±30 ppm tolerance. Consider the 80 ohm ESR limit when designing drive level constraints to prevent over-driving the crystal and ensure long-term aging performance within 5 ppm/year.

Crystals Part Context

This component belongs to the ILCX19 series of parallel fundamental quartz crystals manufactured by ILSI America. The series utilizes AT-cut quartz elements housed in compact ceramic packages. These devices are engineered for general-purpose timing applications where small form factors and cost-effectiveness are prioritized alongside standard frequency stability requirements for digital communication protocols.

Crystals Replacement Considerations

Direct replacements must share the 48 MHz frequency, 10 pF load capacitance, and 4-SMD no-lead package geometry. Verify that substitute parts meet the same 80 ohm ESR maximum and ±30 ppm tolerance limits to maintain circuit compatibility without redesigning the oscillator layout.
