18QHTF21-4.608-PD

Oscillators Overview

The 18QHTF21-4.608-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 4.608 MHz and utilizes LVCMOS output logic. The device is powered by a 1.8V supply voltage and features a power-down standby function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V for energy-efficient applications
• Integrates a power-down standby mode to reduce consumption when inactive
• Provides stable LVCMOS signal output for digital circuit synchronization

Oscillators Applications

• General-purpose clock generation for embedded systems
• Timing reference for microcontrollers and processors
• Synchronization in portable electronic devices requiring low power

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Ensure the 1.8V supply rail is stable and within the operational limits defined in the official datasheet. Confirm that the PCB layout supports the 4-SMD no-lead package footprint to guarantee reliable soldering and electrical performance during assembly.

Oscillators Selection Notes

Select this component when a precise 4.608 MHz timing source is required with minimal power consumption. The 1.8V operating voltage makes it suitable for modern low-power digital designs. Consider the small 2.0x1.6 mm form factor for space-constrained layouts. Ensure compatibility with LVCMOS interfaces commonly found in consumer electronics and industrial control modules.

Oscillators Part Context

This model belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series is characterized by its small footprint and low voltage operation. The 'PD' suffix indicates the inclusion of a power-down feature, distinguishing it from standard continuous-operation variants within the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 4.608 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar low-profile oscillators if availability is an issue.
