18QHTF21-48.416-PD

Overview

The 18QHTF21-48.416-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 48.416 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and features a Standby (Power Down) control function for energy 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 precise clock signals in space-constrained electronic systems.

Feature Summary

• Supports Standby mode for power reduction
• Compact surface-mount form factor
• LVCMOS output compatibility

Applications

• Portable consumer electronics
• Battery-powered devices
• Embedded system clock generation

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD package footprint matches your PCB layout constraints. Check for any specific RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this model when a low-voltage 1.8V operation is required alongside a small physical footprint. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the standby feature if power efficiency during idle periods is a critical design parameter. Verify that the 48.416 MHz frequency meets the exact timing needs of the target application.

Part Context

This part belongs to the 18QHTF21 series of ultra-small crystal oscillators from Mercury Electronics. The series typically offers various frequencies within a 2.0x1.6mm package. These components are positioned as solutions for modern miniaturized electronics where size and power consumption are primary constraints compared to larger traditional oscillator packages.

Replacement Considerations

Direct substitutes may include other 18QHTF21 variants with different frequencies or voltages from the same manufacturer. Cross-referencing with other manufacturers' 2.0x1.6mm LVCMOS oscillators requires careful verification of pinout, voltage levels, and electrical characteristics to ensure functional equivalence.
