18QHTF21-26.040-PD

Oscillators Overview

The 18QHTF21-26.040-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 26.04 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This component is designed for applications requiring precise timing signals within a small form factor.

Oscillators Feature Summary

• Integrates LVCMOS output logic for standard digital interface compatibility
• Supports standby mode to reduce power consumption during idle periods
• Utilizes a leadless SMD package for surface-mount assembly efficiency

Oscillators Applications

• General purpose timing clock generation
• Embedded systems requiring low-power oscillators
• Consumer electronics with space constraints

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead footprint matches your PCB layout specifications to avoid soldering issues. Check for any RoHS compliance documentation if required for your manufacturing standards.

Oscillators Selection Notes

Select this component when a 26.04 MHz frequency is specifically required for system synchronization. Consider the 1.8V operating voltage as a primary constraint for power supply design. The small 2.0x1.6mm package makes it suitable for dense PCB layouts where larger oscillators cannot fit. Evaluate the need for standby functionality if power management is critical to the application.
