18QHTF21-4.910-PD

Oscillators Overview

The 18QHTF21-4.910-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 4.910 MHz and utilizes LVCMOS output logic. The device is designed for a 1.8V supply voltage and features a standby or power-down function to manage energy consumption. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Supports low-power standby mode for energy efficiency
• Utilizes LVCMOS output logic for digital interface compatibility
• Designed for battery-powered and portable electronic devices

Oscillators Applications

• Battery-powered consumer electronics
• Portable computing devices
• General-purpose digital timing circuits

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 4.910 MHz specification. Confirm that the 1.8V operating voltage aligns with the target system design. Ensure the 4-SMD no-lead package dimensions fit the PCB footprint constraints. Check for RoHS compliance status if environmental regulations apply to the end product.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The inclusion of a power-down feature makes it suitable for applications prioritizing extended battery life. Consider the 4.910 MHz frequency requirement specifically, as other variants in the series offer different frequencies.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic, a manufacturer specializing in quartz crystals and oscillators since 1973. The series includes various frequencies such as 4.068 MHz and 96.768 MHz, all sharing similar package and electrical characteristics but differing in output frequency.

Oscillators Replacement Considerations

Direct substitutes within the same series include 18QHTF21-4.068-PD and 18QHTF21-18.1059-PD, provided the frequency difference is acceptable for the application.
