18QHTF21-8.432-PD

Overview

The 18QHTF21-8.432-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 8.432 MHz. It utilizes LVCMOS output logic and functions with a supply voltage of 1.8V. The device features a power-down mode for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

Supports LVCMOS output interface
Includes power-down functionality
Compact surface-mount package

Applications

Battery-powered portable devices
General electronic systems requiring clock signals
Embedded applications with space constraints

Procurement Notes

Verify the specific suffix PD indicates power-down capability rather than other variants like OE. Confirm the 1.8V supply requirement matches the target circuit design. Ensure the 4-SMD no-lead footprint aligns with PCB layout specifications before ordering.

Selection Notes

Choose this component when a low-voltage 1.8V operation is required alongside a small form factor. The power-down feature makes it suitable for applications needing standby current reduction. Verify compatibility with LVCMOS logic levels in the host system.

Part Context

Mercury Electronics Ind. Co. Ltd specializes in frequency control products including quartz crystals and oscillators. This model belongs to their XO series, designed for precise timing applications in consumer and industrial electronics.

Replacement Considerations

Check equivalent models from Mercury Electronics such as 18QHTF21-8.432-OE if enable/disable control is preferred over power-down. Verify pinout and electrical parameters match exactly before substitution.
