18QHTF21-1.0152-PD

Overview

The 18QHTF21-1.0152-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 1.0152 MHz and utilizes an LVCMOS output signal format. The device requires a supply voltage of 1.8V and features a standby or power-down mode for energy management. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby and power-down functionality
• Utilizes LVCMOS output interface

Applications

• Battery-powered electronic devices
• Portable consumer electronics
• General timing applications requiring low power consumption

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Cross-reference the manufacturer datasheet for detailed electrical specifications to guarantee compatibility.

Selection Notes

Select this component when a precise 1.0152 MHz reference is required in space-constrained designs. The 1.8V operating voltage makes it suitable for modern low-power systems. Consider the LVCMOS output compatibility with your digital logic levels. The small 2.0x1.6 mm package aids in miniaturization efforts compared to larger oscillator packages.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in frequency control products including quartz crystals and oscillators. The manufacturer has been active in the industry since 1973. This series typically offers various frequencies within a standardized small outline package, catering to diverse timing needs in compact electronic assemblies.

Replacement Considerations

Direct substitutes must match the 1.0152 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead 2.0x1.6 mm package. Verify pinout compatibility and electrical characteristics such as current consumption and startup time. Generic replacements may differ in stability or phase noise performance.
