18QHTF21-4.0001-OE

Oscillators Overview

The 18QHTF21-4.0001-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 4.0001 MHz and utilizes LVCMOS output logic. The device is powered by a 1.8V supply voltage and features an enable/disable function for power management. It is housed in a compact 4-SMD, No Lead package suitable for surface-mount applications. The unit maintains a frequency stability of ±50ppm and functions reliably within an operating temperature range of -40°C to 85°C.

Oscillators Feature Summary

• Supports enable and disable functionality for efficient power control
• Delivers LVCMOS output signals for digital interface compatibility
• Designed for surface-mount integration with a leadless SMD package

Oscillators Applications

• Consumer electronics requiring precise timing references
• Industrial control systems operating in variable temperatures
• Communication devices utilizing standard clock frequencies

Oscillators Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm the exact enable/disable configuration and pinout arrangement. Ensure the selected variant matches the required 1.8V supply specification and LVCMOS output levels for your circuit design. Cross-reference the package dimensions with your PCB footprint requirements before finalizing procurement decisions.

Oscillators Selection Notes

Choose this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The ±50ppm stability suits general-purpose timing needs rather than high-precision navigation or telecommunications. Consider the enable feature if system-wide power reduction during idle states is a priority. Evaluate thermal performance within the specified -40°C to 85°C range for environmental suitability.

Oscillators Part Context

This oscillator belongs to the Mercury Electronic Ind. Co. Ltd series of surface-mount timing devices. The brand specializes in quartz-based frequency control products including crystals, filters, and oscillators. This specific model represents a standard fixed-frequency solution designed for compact electronic assemblies where space constraints and moderate stability are key design factors.

Oscillators Replacement Considerations

Direct substitutes include other 4.0001 MHz LVCMOS oscillators from Mercury such as the 18QHTF21-4.000-OE, provided the enable function and package match. Verify equivalent supply voltage and stability specifications when considering alternatives from different manufacturers to ensure signal integrity and thermal compliance.
