18QHTF21-106.250-PD

Overview

The 18QHTF21-106.250-PD is a crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 106.25 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a Standby (Power Down) control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This component is engineered for standard clock signal generation applications requiring low power consumption.

Feature Summary

• Supports Low Voltage CMOS (LVCMOS) output logic levels
• Integrates a Standby or Power Down control pin for energy management
• Utilizes a leadless surface-mount package design

Applications

• Battery-powered portable electronic devices
• General-purpose digital clock signal generation
• Low-power embedded system timing references

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead footprint matches your PCB land pattern. Check for RoHS compliance status if required by your manufacturing standards. Request official datasheets to validate electrical characteristics for final integration.

Selection Notes

Select this model when a 106.25 MHz clock source is required with strict low-voltage constraints. The 1.8V operation makes it suitable for modern portable electronics where power efficiency is critical. The standby feature allows for significant power savings during idle periods. Consider the small 2.0x1.6mm package size for space-constrained board layouts. Ensure compatibility with LVCMOS interfaces in the target application.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in frequency control products. The series includes various frequencies such as 18.1059 MHz, 68.08 MHz, and 81.25 MHz.
