LFXTAL078426BULK

Overview

The LFXTAL078426BULK is a fundamental mode quartz crystal resonator manufactured by IQD Frequency Products. It operates at a nominal frequency of 30 MHz with a load capacitance of 30 pF and an equivalent series resistance (ESR) of 40 Ohms. The component features a frequency tolerance of ±50 ppm and a maximum annual aging rate of ±5 ppm. It is housed in a radial HC-49/4H package, measuring approximately 11.05 mm in length, 4.7 mm in width, and 4.1 mm in height. The device supports a drive level of 1 mW and functions within an operating temperature range of -20°C to +70°C.

Feature Summary

Procurement Notes

Verify the specific suffix designation against official IQD documentation to confirm exact electrical tolerances and packaging configuration. Ensure that the selected variant matches the required load capacitance and frequency stability specifications for the target circuit design. Confirm compliance with relevant environmental directives prior to integration.

Selection Notes

Select this component when a through-hole quartz crystal is required for 30 MHz applications. Consider the HC-49/4H package dimensions for PCB layout constraints. Evaluate the ±50 ppm initial tolerance and ±5 ppm/year aging against system requirements. Verify that the 1 mW drive level is compatible with the oscillator circuit's output impedance.
