HC49US-FF3F18-10.000MHZ

Crystals Overview

The ILSI HC49US-FF3F18-10.000MHZ is a fundamental parallel quartz crystal operating at a nominal frequency of 10 MHz. It features a frequency stability and tolerance of ±30 ppm, with a load capacitance of 18 pF and an equivalent series resistance (ESR) of 60 Ohms. The component utilizes AT-cut technology for reliable performance across a temperature range of -40°C to +85°C. Designed for through-hole mounting in the standard HC-49/US package, it measures approximately 11.05 mm in length, 4.65 mm in width, and 13.45 mm in height. The device supports lead-free processing and complies with RoHS standards.

Crystals Feature Summary

• Fundamental parallel quartz crystal construction utilizing AT-cut technology
• Through-hole mounting capability within the standard HC-49/US metal package
• Compliance with lead-free processing requirements and RoHS standards

Crystals Applications

• General-purpose clock signal generation in digital circuits
• Microcontroller and microprocessor system timing references
• Communication equipment requiring stable 10 MHz base frequencies

Crystals Procurement Notes

Verify that the specific part number matches the required 10 MHz frequency and 18 pF load capacitance specifications. Confirm compatibility with through-hole assembly processes and ensure the operating temperature range meets the application's environmental requirements. Check for RoHS compliance documentation if restricted substances are a concern.

Crystals Selection Notes

Select this component when a fundamental mode crystal with ±30 ppm stability is required for through-hole applications. Consider the 60 Ohm ESR value for oscillator circuit design to ensure proper startup conditions. Ensure the physical dimensions of the HC-49/US package fit the available PCB space and mounting constraints.

Crystals Part Context

This component belongs to the HC49US series of quartz crystals manufactured by ILSI America. The series offers various frequency options within the same standardized package form factor. These crystals are designed for cost-effective mass production while maintaining consistent electrical performance across different operating temperatures.

Crystals Replacement Considerations

The HC49US-FF3F18-12.000MHZ serves as a substitute within the same series but operates at 12 MHz rather than 10 MHz. Verify that the frequency difference does not impact the target circuit's timing requirements before substitution.
