18QHTF21-2.200-PD

Oscillators Overview

The 18QHTF21-2.200-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a fixed frequency of 2.2 MHz. It utilizes LVCMOS output logic and supports a supply voltage of 1.8V with an integrated standby or power-down function for energy management. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, designed for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated standby mode for power reduction
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• Low-frequency clock signal generation
• Embedded system timing references
• Portable electronic devices requiring low power consumption

Oscillators Procurement Notes

Verify the specific manufacturer part number against official Mercury Electronics documentation to ensure authenticity. Confirm that the required supply voltage and output logic levels match the target circuit design. Check for any specific handling requirements associated with the small form factor SMD package during assembly.

Oscillators Selection Notes

Select this component when a precise 2.2 MHz clock source is required with low voltage operation. Ensure the application can accommodate the 1.8V supply constraint and benefits from the power-down feature. Verify that the physical footprint fits within the available PCB space constraints.

Oscillators Part Context

This model belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options, all sharing a consistent 2.0x1.6 mm package size. This specific variant provides a lower frequency option compared to higher-speed models in the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 2.2 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD package. Cross-reference with other manufacturers offering identical pinout and electrical specifications to ensure functional interchangeability without circuit modification.
