18QHTF21-36.621094-PD

Oscillators Overview

The 18QHTF21-36.621094-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 36.621094 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and 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 component supports an operating temperature range of -40°C to +85°C and maintains a frequency stability of ±50ppm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V with LVCMOS output compatibility
• Includes standby mode functionality for power reduction
• Utilizes a miniature surface-mount package for space-constrained designs

Oscillators Applications

• Embedded systems requiring precise clock synchronization
• Consumer electronics utilizing low-power microcontrollers
• Industrial control modules operating in extended temperature ranges

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply rail is stable within the specified limits to ensure accurate oscillation. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions precisely to avoid assembly issues. Check for any specific handling instructions regarding electrostatic discharge during installation.

Oscillators Selection Notes

Select this component when a fixed frequency near 36.6 MHz is required with strict size constraints. The 1.8V supply requirement makes it suitable for modern low-power digital circuits. Consider the ±50ppm stability if higher precision is needed, as other variants may offer tighter tolerances. The standby feature is advantageous for battery-operated devices requiring periodic sleep modes.

Oscillators Part Context

This part belongs to the QHTF series of high-frequency crystal oscillators from Mercury Electronics. The series is characterized by small form factors and low power consumption. The '18' prefix typically indicates the 1.8V supply voltage variant, while '21' denotes the package type. These components are designed for applications demanding reliable timing signals in compact electronic assemblies.

Oscillators Replacement Considerations

Direct replacements must match the 36.621094 MHz frequency, 1.8V supply, and 4-SMD No Lead package. Verify that substitute parts support LVCMOS outputs and similar frequency stability. Cross-reference pinouts and thermal characteristics to ensure compatibility with existing board layouts.
