18QHTF21-7.600-PD

Overview

The 18QHTF21-7.600-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 7.6 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features a standby power-down mode for energy efficiency. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The component supports an operating temperature range suitable for general electronic applications.

Feature Summary

• LVCMOS output logic interface
• Standby power-down capability
• Compact 4-SMD no-lead surface mount package

Applications

• Battery-powered portable devices
• General purpose clock generation
• Embedded systems requiring low power consumption

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD package footprint matches your PCB layout constraints. Check for any specific RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a small form factor. The LVCMOS output is suitable for direct interfacing with digital logic circuits. Consider the standby feature if power management during idle periods is critical to your application's battery life or thermal profile.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 2.0x1.6mm package. The series is designed for applications demanding precise timing in space-constrained environments. Mercury Electronics has a long history in quartz crystal manufacturing, providing reliable frequency control solutions.

Replacement Considerations

Direct substitutes must match the 7.6 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pin compatibility and electrical characteristics such as current consumption and startup time. Cross-reference with other manufacturers offering similar ultra-small oscillators.
