18QHTF21-3.510-PD

Oscillators Overview

The 18QHTF21-3.510-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind., Co., Ltd. It operates at a frequency of 3.510 MHz and utilizes LVCMOS output logic levels. The device is designed for low-power applications, featuring a supply voltage of 1.8V and supporting a standby or power-down mode to minimize energy consumption during inactive periods. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• Supports low-voltage operation with 1.8V supply
• Includes standby function for power reduction
• Provides LVCMOS signal output compatibility

Oscillators Applications

• Portable electronic devices requiring low power consumption

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Confirm that the 1.8V operating voltage aligns with your system's power rail availability and that the LVCMOS interface is compatible with the receiving logic inputs.

Oscillators Selection Notes

Select this component when a precise 3.510 MHz reference is required in space-constrained designs. The choice is driven by the need for low voltage operation and power-down capabilities. Consider the 4-SMD package size for board density. Verify that the manufacturer's specified stability meets the application's timing accuracy needs compared to alternative frequencies or packages.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronic Ind., Co., Ltd. The series offers various frequency options within a standardized small outline package. Mercury Electronics is a specialized supplier of frequency control products, including quartz crystals and oscillators, with a long history in the industry.
