18QHTF21-7.0333-OE

Overview

The 18QHTF21-7.0333-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a nominal frequency of 7.0333 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and features an Enable/Disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. The component supports an operating temperature range suitable for industrial applications and offers a base resonator type of Crystal.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes Enable/Disable pin for active power management
• Utilizes a compact 4-SMD No Lead surface-mount package

Applications

• Embedded systems requiring precise clock signals
• Consumer electronics with low-power constraints
• Industrial control modules needing stable timing references

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 PCB footprint matches the 2.0x1.6mm 4-SMD No Lead package dimensions to prevent assembly issues. Check availability through authorized distributors as stock levels may vary.

Selection Notes

Select this component when a low-profile, 1.8V LVCMOS oscillator is required for space-constrained designs. Consider the 7.0333 MHz frequency specifically for communication protocols or timing circuits that do not require higher frequencies. Evaluate the Enable/Disable feature if dynamic power saving is critical for the application. Compare against other Mercury models in the 18QHTF series for alternative form factors or voltages.

Part Context

This part belongs to the 18QHTF series from Mercury Electronic Ind. Co., Ltd., a manufacturer specializing in quartz crystals and oscillators since 1973. The series is known for providing standard XO solutions with various frequency options and supply voltages. Mercury is recognized as a pioneer in the Taiwanese crystal industry, offering reliable frequency control products for global electronic markets.

Replacement Considerations

Direct substitutes within the same series include other variants such as 18QHTF21-50.0333-OE or 18QHTF21-83.0333-OE, provided the frequency difference is acceptable for the application. Verify that any replacement maintains the 1.8V supply requirement and LVCMOS output logic. Cross-reference package dimensions to ensure mechanical compatibility on the PCB.
