18QHTF21-23.450-PD

Oscillators Overview

The 18QHTF21-23.450-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd, operating at a fixed frequency of 23.45 MHz. It utilizes LVCMOS output logic and supports a supply voltage range typically associated with the 1.8V standby power-down feature indicated in its model designation. The component is housed in a compact 4-SMD, No Lead surface-mount package with dimensions of 2.00mm x 1.60mm and a maximum height of 2.00mm. This series is designed for applications requiring precise timing signals in space-constrained electronic systems.

Oscillators Feature Summary

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V standby specification aligns with your system's power management strategy. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any specific handling precautions related to the no-lead package type during assembly processes.

Oscillators Selection Notes

Select this component when a 23.45 MHz frequency is required within a minimal footprint constraint. Consider the LVCMOS output level compatibility with your downstream logic family. Evaluate the thermal performance if the device will operate near its maximum rated temperature limits. Compare against other Mercury 18QHTF21 variants if different frequencies or voltage levels are needed for alternative system configurations.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequency options within a standardized small outline package. The 'PD' suffix likely indicates specific packaging or power-down characteristics distinct from standard variants. This series represents Mercury's capability in producing high-reliability quartz-based frequency control products for modern electronic assemblies.

Oscillators Replacement Considerations

Direct replacements must match the 23.45 MHz frequency, LVCMOS output, and 4-SMD package dimensions. Verify pinout compatibility if substituting with similar packages from other manufacturers. Ensure the replacement component meets the same electrical specifications regarding supply voltage and current consumption. Cross-reference with Mercury's official substitution guide for equivalent parts within their product line.
