LFXTAL035293

Overview

LFXTAL035293 is a fundamental mode quartz crystal resonator manufactured by IQD Frequency Products. It operates at a nominal frequency of 12 MHz with a load capacitance of 16 pF. The component features a frequency tolerance of ±30 ppm and a frequency stability of ±50 ppm over the operating temperature range. It utilizes an HC-49/4H through-hole package, measuring 11.05 mm in length, 4.7 mm in width, and 4.1 mm in height. The equivalent series resistance (ESR) is specified at 40 ohms.

Feature Summary

• Fundamental mode oscillation for precise timing applications
• Through-hole mounting via HC-49/4H package for robust mechanical connection
• Defined load capacitance compatibility for standard oscillator circuits

Applications

• General-purpose clock generation in digital logic systems
• Microcontroller and microprocessor timing references
• Industrial control equipment requiring stable frequency sources

Procurement Notes

Verify the specific packaging configuration upon ordering, as bulk availability may vary. Confirm that the HC-49/4H form factor aligns with the target PCB footprint requirements. Ensure the operating temperature range meets the environmental specifications of the end application to maintain the stated frequency stability and tolerance parameters.

Selection Notes

Select this component when a fundamental mode crystal is required for 12 MHz applications. The HC-49/4H package suits designs needing through-hole assembly rather than surface mount alternatives. Consider the 40 ohm ESR value to ensure compatibility with the driving circuit's power limitations and oscillation startup conditions within the system design.

Part Context

This part belongs to the LFXTAL series of quartz crystals from IQD Frequency Products. It serves as a passive frequency-determining element, distinct from active clock oscillators. The HC-49/4H package is a standard industry format for through-hole mounted resonators, providing a reliable solution for general electronics timing needs.

Replacement Considerations

Direct substitutes must match the 12 MHz frequency, 16 pF load capacitance, and HC-49/4H package dimensions. Verify that alternative components meet or exceed the ±30 ppm tolerance and ±50 ppm stability specifications to ensure functional equivalence in the circuit.
