18QHTF21-3.070-PD

Oscillators Overview

The 18QHTF21-3.070-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 3.07 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features a Standby (Power Down) control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm. This component is designed for timing applications requiring low voltage operation and small form factor integration.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes Standby (Power Down) functionality to reduce power consumption
• Utilizes a 4-SMD, No Lead surface-mount package for space-constrained designs

Oscillators Applications

• Battery-powered portable electronic devices
• Low-voltage digital circuit timing references
• Compact consumer electronics requiring minimal board space

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 4-SMD No Lead footprint matches your PCB layout specifications. Check for any RoHS compliance documentation if required by your manufacturing standards. Validate availability through authorized distributors as stock levels may vary.

Oscillators Selection Notes

Select this component when a 3.07 MHz clock signal is specifically required for LVCMOS interfaces. Consider the 1.8V operating voltage constraint to ensure compatibility with low-power microcontrollers or FPGAs. The small 2.0x1.6mm package makes it suitable for high-density PCB layouts. Evaluate the standby feature benefits if power efficiency is a critical design parameter compared to continuous-operation oscillators.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd., a manufacturer specializing in quartz crystals and oscillators. The series typically offers various frequencies within a standardized 4-SMD package. Mercury Electronics has been producing frequency control products since 1973, focusing on Taiwan-based manufacturing. The 'PD' suffix likely indicates a specific pin configuration or packaging variant within their product line.

Oscillators Replacement Considerations

Direct substitutes must match the 3.07 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify equivalent electrical characteristics such as phase noise and stability if available. Cross-reference with other manufacturers offering similar low-profile XO components. Ensure the replacement supports the same standby control functionality if power management is utilized.
