18QHTF21-10.368-PD

Overview

The 18QHTF21-10.368-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 10.368 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and features a Standby (Power Down) control function. 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 for power efficiency
• Includes standby mode capability to reduce power consumption
• Utilizes LVCMOS output logic for digital interface compatibility

Applications

• Battery-powered portable electronic devices
• Digital communication systems requiring precise timing
• Embedded microcontroller clock sources

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 no-lead package footprint matches your PCB layout constraints. Check for any specific manufacturing date codes or lot traceability requirements if applicable to your quality standards.

Selection Notes

Select this component when a small form factor is required alongside low power consumption. The 1.8V operating voltage makes it suitable for modern low-voltage digital circuits. The integrated standby feature allows for dynamic power management. Consider the 10.368 MHz frequency specifically for applications requiring division into common baud rates or video timing standards.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The manufacturer has decades of experience in Taiwan producing crystals and oscillators. This series typically offers various frequencies within a standardized small SMD package, catering to consumer electronics and industrial timing needs.

Replacement Considerations

Direct substitutes must match the 10.368 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as current consumption and startup time. Cross-reference with other manufacturers offering similar low-profile oscillators with standby functionality.
