18QHTF21-6.250-PD

Overview

The 18QHTF21-6.250-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 6.25 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features a standby mode for power down functionality. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications.

Feature Summary

• Supports low-power standby mode for energy efficiency
• Utilizes LVCMOS output logic for digital interface compatibility
• Compact 4-SMD no-lead package design

Applications

• Battery-powered portable devices
• General-purpose digital clocking
• Embedded system timing references

Procurement Notes

Verify the specific ordering suffix and frequency tolerance against the official datasheet before procurement. Ensure the selected variant matches the required supply voltage and output logic levels for your circuit design to avoid compatibility issues.

Selection Notes

Select this component when a 6.25 MHz reference with LVCMOS outputs is required in a small footprint. Consider the 1.8V supply constraint and standby capability for power-sensitive designs. Verify package dimensions against PCB layout constraints.

Part Context

This part belongs to the Mercury Electronics SMD oscillator series, which includes various frequencies and packages. The '18' prefix typically indicates the 1.8V supply voltage range, while 'QHTF' denotes the specific series characteristics within their quartz-based product line.

Replacement Considerations

Direct substitutes must match the 6.25 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD package. Check manufacturer cross-reference lists for pin-compatible alternatives with identical electrical specifications.
