18QHTF21-10.025-OE

Overview

The 18QHTF21-10.025-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.025 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby mode capability for power reduction
• Utilizes a leadless surface-mount package design

Applications

• General timing reference for electronic circuits
• Clock signal generation in consumer electronics
• Embedded system clock sources

Procurement Notes

Verify the exact operating temperature range and load capacitance requirements against the specific application needs before procurement. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout constraints to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 10.025 MHz frequency. The LVCMOS output is suitable for standard digital logic families. Consider the small 2.0x1.6 mm package size if space constraints are critical. Verify that the standby feature meets power efficiency goals compared to continuous-operation alternatives.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options within a consistent 4-SMD no-lead form factor. This specific model provides a 10.025 MHz output, distinguishing it from other variants like the 25.020 MHz or 21.200 MHz models in the same family.

Replacement Considerations

Direct substitutes include other 10.025 MHz LVCMOS oscillators in 4-SMD packages from Mercury Electronics, such as the 18QHTF21-10.025-PD, provided the pinout and electrical specifications match exactly.
