18QHTF21-33.000-PD

Oscillators Overview

The 18QHTF21-33.000-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 33.0 MHz with an LVCMOS output logic type. The device requires a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. This component is designed for applications requiring precise clock signals within a small form factor.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby and power-down functionality to reduce power consumption
• Utilizes a compact 4-SMD no-lead surface mount package

Oscillators Applications

• General purpose clock signal generation
• Digital system timing references
• Embedded electronics requiring low-profile oscillators

Oscillators Procurement Notes

Verify the specific ordering suffix and manufacturer part number against official Mercury Electronics documentation to ensure correct specifications. Confirm that the 1.8V supply voltage and LVCMOS output align with your circuit design requirements. Check for any specific handling instructions related to the 4-SMD no-lead package during assembly.

Oscillators Selection Notes

Select this component when a 33.0 MHz clock source is required with a 1.8V operating voltage. Ensure the PCB layout supports the 2.0 x 1.6 mm footprint. Consider the standby feature if power efficiency is a priority. Verify that LVCMOS logic levels are compatible with the receiving digital components in the system.

Oscillators Part Context

This oscillator belongs to the QHTF21 series from Mercury Electronic Ind. Co., Ltd., which specializes in quartz crystals and frequency control products. The company has a long history in manufacturing precision frequency components. This specific model represents a standard XO variant optimized for modern electronic devices needing reliable timing solutions.

Oscillators Replacement Considerations

Direct substitutes must match the 33.0 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Cross-reference with other Mercury Electronics models in the same series or comparable industry offerings that meet these exact electrical and mechanical constraints.
