18QHTF21-10.1313-PD

Overview

The 18QHTF21-10.1313-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.1313 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and features a Standby (Power Down) function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports standby mode for power reduction
• Utilizes LVCMOS output interface
• Compact surface-mount package design

Applications

• Portable electronic devices
• Battery-powered systems
• General purpose timing circuits

Procurement Notes

Verify the specific suffix 'PD' indicates the Standby feature when sourcing replacements. Confirm the 1.8V operating voltage matches the target circuit requirements. Ensure the 4-SMD no-lead footprint aligns with the PCB layout specifications to guarantee proper mechanical fit and electrical connectivity during assembly.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside active power-down capabilities. The small 2.0x1.6mm form factor makes it suitable for space-constrained designs. Consider the LVCMOS output compatibility with downstream digital logic interfaces before finalizing the bill of materials.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz timing solutions. The manufacturer has decades of experience in Taiwan's frequency control industry. This specific model represents a standard XO variant designed for modern portable applications requiring efficient power management.

Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical pinout and voltage but different frequencies, such as 18QHTF21-13.1313-PD or 18QHTF21-51.200-PD, provided the system clock requirement changes.
