18QHTF21-7.370-PD

Overview

The 18QHTF21-7.370-PD is a 7.37 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a supply voltage of 1.8V and utilizes LVCMOS output logic. The component features a Standby function for power management, allowing for power-down states. It is housed in a compact 4-SMD package with no lead configuration, measuring 2.0mm by 1.6mm in dimensions. This surface-mount device is designed for standard frequency control applications requiring low voltage operation.

Feature Summary

• Supports LVCMOS output interface for digital circuit compatibility
• Includes standby capability to reduce power consumption during idle periods
• Utilizes a lead-free 4-SMD surface-mount package for automated assembly

Applications

• Portable electronic devices requiring low-voltage clock sources
• Communication modules utilizing standard LVCMOS interfaces
• Embedded systems needing compact frequency control solutions

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. Confirm that the 1.8V operating voltage aligns with your system's power rails. Ensure the 2.0x1.6mm footprint matches your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards. Validate the supplier's authenticity through official Mercury Electronics channels.

Selection Notes

Select this component when a 7.37 MHz frequency is specifically required for LVCMOS-based designs. Consider the 1.8V supply constraint as a primary selection criterion. Evaluate the small 2.0x1.6mm package size against available board space. Compare the standby feature benefits against power budget requirements. Ensure compatibility with existing clock distribution networks in the target application.

Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency oscillators. The manufacturer has extensive experience in quartz crystal production since 1973. The 18QHTF21 series typically offers various frequencies within a compact SMD form factor. These components are designed for general-purpose timing applications in consumer and industrial electronics.

Replacement Considerations

Direct substitutes include other 7.37 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical parameters before substitution. Alternative models from Mercury Electronics may offer different frequencies or voltages but require design review.
