Overview
The LFXTAL024944B is a through-hole quartz crystal manufactured by IQD Frequency Products. It operates at a nominal frequency of 16 MHz with a tolerance of ±30 ppm and stability of ±50 ppm over the operating temperature range. The component utilizes an HC-49/4H package, measuring 11.05 mm in length, 4.7 mm in width, and 4.1 mm in height. It features a load capacitance of 30 pF, an equivalent series resistance (ESR) of 40 Ohms, and a maximum drive level of 500 uW. The device supports radial termination for PCB mounting.
Feature Summary
- Provides stable oscillation at 16 MHz within specified tolerance limits
- Designed for reliable performance across industrial temperature ranges
- Utilizes standard HC-49/4H housing for easy integration
Applications
- General-purpose clock signal generation
- Microcontroller timing circuits
- Communication interface synchronization
Procurement Notes
Verify the specific suffix and packaging configuration when ordering, as bulk quantities may differ from single-unit availability. Confirm that the HC-49/4H form factor aligns with existing board layouts. Ensure the 30 pF load capacitance matches the oscillator circuit design requirements to maintain frequency accuracy. Cross-reference the manufacturer part number with distributor catalogs to identify any alternative reel or bulk options.
Selection Notes
Select this component when a 16 MHz reference is required for through-hole assembly. The HC-49/4H package offers mechanical robustness compared to surface-mount alternatives. Consider the 40 Ohm ESR value for circuit impedance matching. The ±30 ppm tolerance is suitable for applications not requiring high-precision timing. Evaluate the 500 uW drive level to prevent over-driving the crystal element.
Part Context
This part belongs to the LFXTAL series of quartz crystals produced by IQD Frequency Products. The series includes various frequencies and packages tailored for different electronic needs. The HC-49/4H designation indicates a specific cylindrical metal can style commonly used in legacy and industrial designs. IQD supplies these components for global electronics manufacturing.
