18QHTF21-3.328-PD

Oscillators Overview

The 18QHTF21-3.328-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 3.328 MHz and utilizes LVCMOS output logic. The device is designed for 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 2.0x1.6mm. This component is engineered for precise timing applications requiring low profile and reliable performance.

Oscillators Feature Summary

• Integrates LVCMOS output logic for standard digital interface compatibility
• Features a dedicated standby mode to reduce power consumption during idle periods
• Utilizes a miniature 4-SMD no-lead surface mount package for space-constrained designs

Oscillators Applications

• General purpose clock generation in embedded systems
• Timing reference for microcontrollers and processors
• Data communication interfaces requiring stable clock signals

Oscillators Procurement Notes

Verify the specific suffix (PD) against official Mercury Electronics documentation to confirm the presence of the power-down feature and exact electrical characteristics. Ensure the operating temperature range meets your application requirements. Cross-reference the package outline drawing to confirm mechanical fit within the PCB layout constraints before finalizing procurement.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is available and a small footprint is critical. The LVCMOS output is suitable for standard CMOS logic families. Consider the power-down capability if battery life or thermal management is a priority. Verify that the 3.328 MHz frequency aligns with the system's baud rate or clock division requirements.

Oscillators Part Context

This part belongs to the 18QHTF21 series of SMD oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within a standardized 2.0x1.6mm package. The 'PD' suffix generally indicates a specific pinout or functional variant, such as the inclusion of a control pin for standby operation, distinguishing it from standard continuous-output models.

Oscillators Replacement Considerations

Direct substitutes must match the 1.8V supply, LVCMOS output, 4-SMD 2.0x1.6mm package, and standby functionality. Check datasheets for compatible parts from other manufacturers offering identical pinouts and electrical specifications to ensure drop-in replacement capability without circuit modification.
