18QHTF21-25.011-PD

Oscillators Overview

The 18QHTF21-25.011-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 25.011 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and includes a standby (power down) function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Supports low voltage operation at 1.8V
• Integrates standby power management capability
• Provides standard LVCMOS signal output

Oscillators Applications

• General purpose clock generation
• Digital circuit timing synchronization
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 2.0x1.6mm footprint matches the PCB layout constraints to avoid assembly issues.

Oscillators Selection Notes

Select this component when a precise 25.011 MHz reference is required for low-power applications. The choice depends on the compatibility of the LVCMOS interface with the receiving logic family. Consider the physical size constraints of the 4-SMD package during the mechanical design phase.

Oscillators Part Context

This model belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series is characterized by small form factors and standardized electrical interfaces. The 'PD' suffix typically indicates the inclusion of a power-down control feature within the device architecture.

Oscillators Replacement Considerations

Direct substitutes must match the 25.011 MHz frequency, 1.8V supply, and LVCMOS output type. Verify pinout compatibility for the 4-SMD No Lead package. Cross-reference with other Mercury QHTF variants or industry-standard equivalents offering identical electrical specifications.
