Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the supply voltage matches the datasheet specifications for the 18V variant if applicable, though standard variants typically operate at lower voltages. Confirm the package orientation and pinout configuration during PCB layout to prevent installation errors. Request the official datasheet from the manufacturer or authorized distributor to validate electrical characteristics and reliability standards prior to ordering.

Oscillators Selection Notes

Select this component when a stable 18 MHz reference is required in space-constrained designs. The LVCMOS output ensures direct interfacing with microcontrollers and FPGAs without additional level shifting. Consider the enable/disable feature if power efficiency is a priority. Compare performance metrics such as phase noise and stability against alternative oscillators from other manufacturers to ensure compliance with system timing budgets and environmental operating conditions.

Oscillators Part Context

This part belongs to the QHTF series of surface-mount crystal oscillators from Mercury Electronics. The series is known for providing reliable frequency control solutions in various electronic devices. The '18' prefix likely indicates a specific voltage or series characteristic, while 'QHTF' denotes the oscillator type. These components are widely used in industries requiring compact, low-power timing sources with standard digital outputs.

Oscillators Replacement Considerations

Direct replacements must match the 18.000 MHz frequency, LVCMOS output, 2.0x1.6mm package, and enable/disable functionality. Verify that substitute parts meet the same electrical specifications and thermal requirements. Cross-reference with similar models from Mercury Electronics or other suppliers offering compatible SMD oscillators.
