HC49USM-FF3F18-6.000 MHZ

Crystals Overview

The ILSI HC49USM-FF3F18-6.000 MHZ is a surface-mount quartz crystal resonator operating at a nominal frequency of 6.000 MHz. It belongs to the HC49USM series and utilizes an AT-cut design for stable performance. The component features a load capacitance of 18 pF and offers a frequency tolerance and stability of ±30 ppm. It has a maximum equivalent series resistance (ESR) of 100 Ω and supports a drive level of 1 mW. The unit operates within a temperature range of -40°C to +85°C and is housed in a standard HC-49/US package measuring 13.3 mm x 4.7 mm.

Crystals Feature Summary

• Surface-mount construction in a compact HC-49/US form factor
• AT-cut quartz element ensures high frequency stability
• Designed for operation across extended industrial temperature ranges

Crystals Applications

• Microcontroller clock generation circuits
• Communication interface timing references
• Digital signal processing systems

Crystals Procurement Notes

Verify that the specific suffix matches the required frequency tolerance and load capacitance for your circuit design. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected packaging option aligns with your automated assembly capabilities. Cross-reference the manufacturer part number against current distributor listings to confirm active production status and availability.

Crystals Selection Notes

Select this component when a 6 MHz surface-mount reference is required with moderate stability specifications. The 18 pF load capacitance must match the oscillator circuit requirements. Consider the 100 Ω ESR limit for driver strength compatibility. This part is suitable for general-purpose digital logic applications where precise timing is needed but extreme precision is not critical.

Crystals Part Context

This model is part of the HC49USM series, which represents a standard surface-mount variant of the traditional HC-49/U through-hole crystal. The series is widely used in consumer electronics and industrial equipment due to its balance of cost, size, and performance. ILSI manufactures these components using established quartz processing techniques to ensure consistent electrical characteristics across production batches.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' HC-49/US crystals with identical 6.000 MHz frequency, 18 pF load capacitance, and ±30 ppm tolerance. Verify mechanical footprint compatibility and soldering profile requirements before substitution.
