18QHTF21-3.5172-PD

Oscillators Overview

The 18QHTF21-3.5172-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind., Co., Ltd. It operates at a fixed frequency of 3.5172 MHz and utilizes LVCMOS output logic. The device is designed for low-power applications, featuring a supply voltage of 1.8V and an integrated standby or power-down function to minimize energy consumption when not in use. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm, suitable for space-constrained surface-mount designs.

Oscillators Feature Summary

• Integrates LVCMOS output logic for direct digital interface compatibility
• Supports standby mode to reduce power consumption during idle periods
• Utilizes a leadless SMD package for automated surface-mount assembly

Oscillators Applications

• Battery-powered portable electronic devices
• Low-power embedded systems requiring precise timing
• Consumer electronics with strict size constraints

Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure the correct package variant and tolerance specifications are selected. Confirm that the 1.8V supply requirement aligns with the target system's voltage rails before integration. Check for any recent updates to the RoHS compliance status or material declarations required for your manufacturing region.

Oscillators Selection Notes

Select this component when a stable 3.5172 MHz reference is needed for LVCMOS-compatible circuits. Ensure the design accommodates the 1.8V operating voltage and provides adequate thermal management for the small footprint. Consider the standby feature if power efficiency is critical for the end application.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic, which specializes in quartz-based frequency control products.
