18QHTF21-12.0305-PD

Overview

The 18QHTF21-12.0305-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 12.0305 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features a power-down (standby) function for energy management. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby mode capability
• Utilizes LVCMOS output interface

Applications

• General clock signal generation
• Embedded system timing references
• Portable electronic devices requiring low power consumption

Procurement Notes

Verify the specific frequency suffix matches the required 12.0305 MHz specification. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD no-lead package footprint fits the PCB layout constraints. Check for any specific handling requirements associated with surface-mount components.

Selection Notes

Select this component when a precise 12.0305 MHz clock source is needed with low voltage compatibility. Consider the small form factor for space-constrained designs. Evaluate the need for standby functionality to manage power states effectively. Compare against other frequencies in the 18QHTF21 series if alternative timing is acceptable.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies within a consistent 2.0x1.6 mm package. These oscillators are designed for applications requiring stable clock signals with minimal power consumption and compact physical dimensions.

Replacement Considerations

Direct substitutes include other variants within the 18QHTF21 series such as 18QHTF21-12.300-PD or 18QHTF21-8.000-PD, provided the frequency difference is acceptable. Verify pinout and electrical characteristics before substitution.
