LFXTAL011164BULK

Overview

The LFXTAL011164BULK is a quartz crystal resonator manufactured by IQD Frequency Products, designed for through-hole mounting applications. It operates at a fundamental frequency of 3.072 MHz with a load capacitance of 20 pF. The component features a frequency tolerance and stability of ±20 ppm and ±50 ppm respectively over the operating temperature range of -10°C to +60°C. Key electrical specifications include an equivalent series resistance (ESR) of 35 Ohms and a drive level of 1 mW. The unit utilizes an HC-49 package with radial leads spaced at 4.88 mm.

Feature Summary

• Provides precise timing signals via fundamental mode quartz resonance
• Supports standard through-hole PCB assembly techniques
• Maintains stable frequency output across defined industrial temperature ranges

Applications

• Microcontroller clock sources requiring 3.072 MHz reference
• Industrial control systems utilizing standard crystal interfaces
• Consumer electronics employing HC-49 form factor components

Procurement Notes

Verify specific lot codes and RoHS compliance status directly with authorized distributors or IQD sales offices before procurement. Confirm that the operating environment remains within the specified -10°C to +60°C thermal limits to ensure long-term reliability. Ensure circuit design accommodates the 1 mW drive level specification to prevent frequency drift or mechanical damage to the quartz element during operation.

Selection Notes

Select this component when a 3.072 MHz fundamental frequency is required for microcontroller or logic circuits. The HC-49 package suits designs prioritizing robust mechanical mounting over space constraints. Verify that the system oscillator circuit can support the 20 pF load capacitance and 35 Ohm ESR characteristics. Consider the ±50 ppm stability rating against the host device's maximum allowable frequency deviation requirements.

Part Context

This part belongs to the LFXTAL series of general-purpose quartz crystals from IQD Frequency Products. The HC-49 package is a widely adopted standard in the industry for through-hole implementations. The 3.072 MHz frequency is commonly derived from higher base clocks for baud rate generation or specific digital timing needs.

Replacement Considerations

Cross-reference with other HC-49/4H or HC-49/U packages offering 3.072 MHz frequency, 20 pF load capacitance, and similar ESR values. Ensure replacement parts match the physical dimensions and lead spacing to maintain board compatibility.
