18QHTF21-1.162-PD

Overview

The 18QHTF21-1.162-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 1.162 MHz with an LVCMOS output logic level. 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 with dimensions of 2.0x1.6mm.

Feature Summary

• Integrates LVCMOS output interface for digital signal compatibility
• Features low power consumption with standby mode capability
• Utilizes surface-mount packaging for automated assembly

Applications

• General clock generation in embedded systems
• Timing reference for microcontrollers
• Low-frequency synchronization circuits

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Ensure the 1.8V supply voltage aligns with the target circuit design. Confirm the 4-SMD no-lead package footprint matches the PCB layout to prevent soldering issues during assembly.

Selection Notes

Select this component when a precise 1.162 MHz timing source is required in space-constrained designs. The 1.8V operating voltage makes it suitable for modern low-voltage digital logic families. Consider the standby feature if power efficiency is a critical system requirement compared to continuous oscillation alternatives.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies within a standardized 2.0x1.6mm SMD form factor. The -PD suffix typically indicates specific pinout or packaging variations within the manufacturer's catalog, ensuring compatibility with standard reflow processes.

Replacement Considerations

Direct substitutes must match the 1.162 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD 2.0x1.6mm package. Verify electrical parameters such as jitter and stability across the operating temperature range to ensure functional equivalence.
