18QHTF21-2.600-OE

Oscillators Overview

The 18QHTF21-2.600-OE is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 2.6 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features enable/disable functionality. It is housed in a 4-SMD, no lead package with dimensions of 2.0mm x 1.6mm. The component supports an operating temperature range from -40°C to 85°C.

Oscillators Feature Summary

• Provides stable clock signals using LVCMOS output logic for digital circuit interfacing.
• Includes hardware control capability through dedicated enable and disable pins.
• Designed for surface-mount assembly within compact electronic systems.

Oscillators Applications

• General-purpose timing reference for embedded microcontrollers
• Clock source for low-frequency digital communication interfaces
• Timing synchronization in consumer electronics devices

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required system clock speed before ordering. Confirm that the 1.8V supply voltage aligns with the target board's power rails. Ensure the 4-SMD no-lead package footprint corresponds to the PCB layout design. Check manufacturer documentation for reflow soldering profile recommendations to prevent thermal damage during assembly.

Oscillators Selection Notes

Select this component when a precise 2.6 MHz clock signal is required for low-power applications. The LVCMOS output is suitable for direct connection to standard logic inputs without additional buffering. Consider the -40°C to 85°C operating range for industrial or commercial environments. The small 2.0x1.6mm package is ideal for space-constrained designs where larger oscillators cannot fit.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent electrical characteristics and packaging. These components are designed to replace through-hole crystals in modern high-density PCB layouts, providing improved reliability and easier automated assembly compared to discrete resonator solutions.

Oscillators Replacement Considerations

Direct substitutes must match the 2.6 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility if swapping between different manufacturers. Ensure equivalent frequency stability and temperature range specifications are met for critical timing applications.
