18QHTF21-13.100-PD

Overview

The 18QHTF21-13.100-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 13.1 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby or power-down feature 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
• Integrates standby and power-down control modes
• Provides LVCMOS digital output signals
• Utilizes a leadless surface-mount package

Applications

• General clock signal generation in embedded systems
• Timing reference for LVCMOS-compatible digital circuits
• Portable electronic devices requiring low-power oscillators

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD no-lead footprint matches the PCB land pattern design to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a precise 13.1 MHz timing source is required for LVCMOS interfaces. The choice is driven by the need for a low-profile, leadless package suitable for space-constrained designs. Consider the 1.8V operating voltage as a primary constraint for compatibility with modern low-power logic families.
