18QHTF21-20.736-PD

Oscillators Overview

The 18QHTF21-20.736-PD is a crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 20.736 MHz and requires a supply voltage of 1.8V. The device supports a standby (power down) function to manage power consumption. It is housed in a compact 4-SMD, no lead surface mount package with dimensions of 2.00mm x 1.60mm. This component is designed for applications requiring precise clock signals in space-constrained electronic systems.

Oscillators Feature Summary

• Supports standby mode for power management
• Compact surface mount package design
• Low voltage operation capability

Oscillators Applications

• Portable electronic devices

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure that the 1.8V supply rail is stable and within the specified operating range to guarantee reliable oscillator performance. Confirm that the PCB footprint matches the 4-SMD no lead package dimensions to avoid assembly issues during manufacturing.

Oscillators Selection Notes

Select this model when a low-profile, surface-mount oscillator is required for 20.736 MHz applications. Consider the 1.8V supply constraint and the availability of standby functionality for power-sensitive designs. Evaluate the thermal characteristics and mounting reliability of the small form factor package relative to the target application environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a standardized 2.0x1.6mm SMD package. The series typically includes options for different supply voltages and output types, catering to diverse consumer and industrial electronics needs while maintaining a consistent physical footprint for design flexibility.

Oscillators Replacement Considerations

Direct substitutes must match the 20.736 MHz frequency, 1.8V supply, and 4-SMD no lead package. Verify pin compatibility and electrical specifications with alternative manufacturers such as Epson or SiTime if sourcing from other vendors.
