18QHTF21-35.4686-PD

Oscillators Overview

The 18QHTF21-35.4686-PD is a 35.4686 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It utilizes LVCMOS output logic and operates on a 1.8V supply voltage. The component features a Standby (Power Down) function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The device ensures frequency stability of ±50ppm and supports an operating temperature range from -40°C to 85°C.

Oscillators Feature Summary

• Supports Standby (Power Down) mode for power management
• Delivers LVCMOS output signal
• Compact 4-SMD No Lead surface mount package

Oscillators Applications

• Digital communication systems requiring precise clock signals
• Embedded control circuits within consumer electronics
• Industrial equipment utilizing standard CMOS logic interfaces

Oscillators Procurement Notes

Verify the specific suffix 'PD' confirms the Power Down functionality when sourcing replacements. Ensure the 1.8V supply requirement aligns with the target circuit design. Confirm the 4-SMD No Lead footprint matches the PCB layout constraints. Check that the ±50ppm stability meets system timing requirements.

Oscillators Selection Notes

Select this component for applications requiring a low-profile 2.0x1.6mm oscillator with integrated power-down capabilities. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the -40°C to 85°C range for general commercial and industrial environments where moderate stability is sufficient.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent 1.8V operation and LVCMOS outputs. The 'PD' designation specifically indicates the inclusion of a standby feature, distinguishing it from continuous-operation variants within the same physical package family.

Oscillators Replacement Considerations

Direct substitutes include other 1.8V LVCMOS oscillators in 4-SMD No Lead packages with similar frequency and stability. Verify pin compatibility and thermal characteristics. Cross-reference with Mercury Electronics' current product listings for updated availability.
