18QHTF21-2.806176-PD

Oscillators Overview

The 18QHTF21-2.806176-PD is a crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 2.806176 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 3.3V and features a Standby (Power Down) control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Compact 4-SMD No Lead surface mount design suitable for high-density PCB layouts
• Integrated standby control capability for power management optimization
• LVCMOS output interface compatible with standard digital logic families

Oscillators Applications

• High-frequency signal generation in portable electronic devices
• Clock source provision for microcontrollers requiring low profile components
• Timing reference in consumer electronics with strict space constraints

Oscillators Procurement Notes

Verify the specific ordering suffix to ensure correct voltage and frequency specifications. Confirm that the 'PD' suffix aligns with the required power-down functionality. Check manufacturer documentation for RoHS compliance status and lead-free soldering recommendations prior to integration into production assemblies.

Oscillators Selection Notes

Select this component when a low-profile 2.0x1.6 mm footprint is mandatory. Ensure the system requires a 3.3V supply and LVCMOS signaling. Consider the standby feature if power efficiency during idle states is a critical design parameter compared to continuous operation oscillators.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz timing solutions. The series includes various frequencies and voltage options. Mercury is a Taiwan-based supplier established in 1973, focusing on crystals, oscillators, and filters for global electronics markets.

Oscillators Replacement Considerations

Direct substitutes include other 2.0x1.6mm LVCMOS oscillators with identical 2.806176MHz frequency and 3.3V operation. Verify pin compatibility and electrical parameters before swapping manufacturers.
