18QHTF21-6.005284-PD

Overview

The 18QHTF21-6.005284-PD is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 6.005284 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby (power down) function for energy management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic for standard digital interfacing
• Integrated standby mode to reduce power consumption
• Compact 4-SMD no-lead surface mount package

Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Request the official datasheet from Mercury Electronics for detailed electrical characteristics and reliability data.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a specific frequency near 6 MHz. The LVCMOS interface is suitable for standard CMOS logic families. Consider the standby feature if power efficiency during idle states is a priority. Verify compatibility with the target application's temperature range and size limitations.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and output types. The 'PD' suffix typically indicates a specific packaging or handling configuration, while the numeric value denotes the nominal frequency. This model provides a stable clock source for compact electronic designs.

Replacement Considerations

Direct substitutes must match the 6.005284 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Check manufacturer cross-reference lists for equivalent parts. Ensure pinout compatibility and thermal performance are identical. Generic oscillators may not fit without design modification.
