18QHTF21-36.1893-PD

Oscillators Overview

The 18QHTF21-36.1893-PD is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 36.1893 MHz with LVCMOS output logic and a supply voltage of 1.8V. The device features a Standby (Power Down) function and is housed in a compact 4-SMD, No Lead package.

Oscillators Feature Summary

• Supports Low Voltage CMOS (LVCMOS) output logic for digital interfacing
• Includes standby capability via power down control
• Utilizes quartz crystal technology for frequency stability

Oscillators Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific suffix 'PD' indicates the Power Down feature when sourcing replacements. Confirm the operating voltage matches the target circuit requirements. Ensure the 4-SMD no-lead package footprint aligns with the PCB design constraints before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 36.1893 MHz reference. The choice depends on the necessity for a power-down state to manage energy consumption during idle periods within the electronic assembly.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface mount oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within a standardized small form factor suitable for space-constrained consumer and industrial electronics applications.

Oscillators Replacement Considerations

Compatible substitutes include other 1.8V LVCMOS oscillators with identical 36.1893 MHz frequency and 4-SMD no-lead packaging. Verify that alternative parts support the same power-down functionality and meet equivalent electrical specifications.
