18QHTF21-37.050-PD

Oscillators Overview

The 18QHTF21-37.050-PD is a crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a nominal frequency of 37.05 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and supports a standby power-down mode for energy efficiency. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This component is designed for applications requiring precise timing signals in space-constrained electronic systems.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V for compatibility with modern digital circuits
• Includes a standby function to reduce power consumption when not in use
• Utilizes a small surface-mount package suitable for high-density PCB layouts

Oscillators Applications

• Portable consumer electronics requiring low power consumption
• Communication modules needing stable clock signals
• Embedded systems with limited board space

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 maintain oscillator performance. Confirm that the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to avoid assembly issues.

Oscillators Selection Notes

Select this model when a 37.05 MHz clock source is required with strict size constraints. Consider the 1.8V supply requirement and ensure compatibility with the target system's voltage levels. Evaluate the need for a power-down feature if battery life or thermal management is a priority in the application design.

Oscillators Part Context

This part belongs to the QHTF series of crystal oscillators from Mercury Electronics, which are known for their compact form factors and reliability. The series typically offers various frequencies and voltage options to suit different embedded applications. The 'PD' suffix indicates the inclusion of a power-down capability, distinguishing it from standard continuous-operation variants within the same family.

Oscillators Replacement Considerations

Direct replacements must match the 37.05 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter before substituting. Consult manufacturer cross-reference lists for officially confirmed equivalent parts.
