18QHTF21-115.333-PD

Overview

The 18QHTF21-115.333-PD is a crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a nominal frequency of 115.333 MHz. It utilizes LVCMOS output logic and functions with a supply voltage of 1.8V. The component features a Standby (Power Down) control mode for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• LVCMOS output interface
• Standby power down capability
• Compact surface mount package

Applications

• Precision frequency generation
• Digital signal processing systems
• Communication equipment

Procurement Notes

Verify the manufacturer part number against official Mercury United Electronics documentation to ensure authenticity. Confirm that the specific frequency tolerance and load capacitance requirements match the target circuit design. Check for any specific ordering suffixes or packaging variations that may affect compatibility.

Selection Notes

Select this component when a 1.8V supply and 115.333 MHz frequency are required in a minimal footprint. Ensure the application supports LVCMOS logic levels and can accommodate the 4-SMD no lead package constraints. Verify thermal and electrical specifications against system requirements.

Part Context

This model belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers standard frequencies with low voltage operation. The PD suffix indicates the inclusion of a power-down feature, distinguishing it from non-stanby variants within the same form factor family.

Replacement Considerations

Direct substitutes must match the 115.333 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics before swapping.
