ILCX19-FF5F10-50.000MHZ

Crystals Overview

The ILCX19-FF5F10-50.000MHZ is a parallel fundamental quartz crystal manufactured by ILSI America, designed for surface mount applications. It operates at a nominal frequency of 50.000 MHz with a load capacitance of 10 pF. The component features a frequency tolerance and stability of ±30 ppm. It utilizes an AT-cut resonator housed in a 4-pin ultra-miniature SMD package measuring 2.0 mm x 1.6 mm. The equivalent series resistance (ESR) is specified as 80 ohms maximum for the 40.0 MHz to 60.0 MHz range. The device supports a drive level of 100 µW and exhibits aging of 5 ppm per year.

Crystals Procurement Notes

Verify that the specific part number suffix matches the required load capacitance and frequency tolerance before procurement. Confirm that the ordering suffix corresponds to the correct packaging format, such as tape and reel specifications. Ensure compatibility with lead-free soldering processes if required by the assembly line. Cross-reference the ESR value against the oscillator circuit design requirements to guarantee stable startup conditions.

Crystals Selection Notes

Select this component when a 50 MHz reference signal is required in space-constrained designs. The 10 pF load capacitance must match the oscillator circuit's external capacitors to achieve the specified ±30 ppm accuracy. Consider the 80 ohm ESR limit to ensure sufficient loop gain. The compact 2.0 x 1.6 mm footprint allows for high-density PCB layouts suitable for portable or embedded wireless applications.

Crystals Part Context

This part belongs to the ILCX19 series of ultra-miniature crystals from ILSI America. The series offers various frequencies and load capacitances within a standardized 4-pin SMD form factor. These components are engineered for cost-effective mass production while maintaining strict frequency stability. The series supports a wide range of digital communication and computing applications requiring precise timing references.

Crystals Replacement Considerations

Direct substitutes within the ILCX19 series include variants with different load capacitances or tolerances, such as ILCX19-FF5F18-50.000MHZ. Verify that any replacement maintains the same physical dimensions and pin configuration. Ensure the alternative part meets the same electrical parameters, specifically the 50 MHz frequency and 10 pF load requirement.
