18QHTF21-13.2531-PD

Overview

The 18QHTF21-13.2531-PD is a crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 13.2531 MHz with LVCMOS output logic. The device supports a supply voltage of 1.8V and includes standby (power down) functionality. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Hermetic ceramic leadless SMD construction for environmental stability
• Integrated standby mode for power management
• LVCMOS output interface compatibility

Applications

• High-frequency clock generation in digital systems
• Precision timing reference for communication modules
• Embedded system clock sources requiring low profile

Procurement Notes

Verify the specific ordering suffix to ensure correct frequency and package configuration. Confirm that the 1.8V supply requirement aligns with the target circuit design. Check datasheet specifications for operating temperature range and load capacitance requirements before integration.

Selection Notes

Select this component when a hermetic, low-profile oscillator is required for 13.2531 MHz applications. Ensure the 1.8V supply voltage matches the system architecture. Consider the 4-SMD no-lead package for space-constrained PCB layouts requiring surface mount assembly.

Part Context

This part belongs to the QHTF series from Mercury Electronics, which offers various hermetic ceramic leadless packages. The series supports frequencies from 1.0 MHz to 200 MHz across multiple supply voltages. Mercury Electronics has decades of experience in quartz crystal manufacturing, positioning this as a reliable frequency control solution.

Replacement Considerations

Direct substitutes within the same series include other frequency variants such as 18QHTF21-18.1059-PD or 18QHTF21-51.200-PD if frequency adjustment is permissible. Verify pinout and electrical characteristics match before substitution.
