18QHTF21-37.125-PD

Oscillators Overview

The 18QHTF21-37.125-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 37.125 MHz with an LVCMOS output logic. The device requires a 1.8V supply voltage and features a standby (power down) function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm. The unit supports a frequency stability of ±50ppm and functions within an operating temperature range of -40°C to +85°C.

Oscillators Feature Summary

• Supports standby mode for power reduction
• Compact surface-mount package design
• LVCMOS output interface compatibility

Oscillators Applications

• Portable electronic devices requiring low power consumption
• Communication systems utilizing standard clock signals
• Embedded control circuits needing precise timing references

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Ensure the 1.8V supply rail is stable and within the specified operating limits. Confirm that the PCB footprint matches the 4-SMD no-lead package dimensions to prevent assembly errors during manufacturing.

Oscillators Selection Notes

Choose this component when a small form factor and low voltage operation are critical. The LVCMOS output ensures compatibility with standard digital logic families. Consider the ±50ppm stability requirement relative to your system's jitter sensitivity. The standby feature makes it suitable for battery-operated applications where power efficiency is a priority.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies with consistent electrical characteristics. The 'PD' suffix indicates the inclusion of a power-down capability. These components are designed for high-volume production environments requiring reliable timing solutions.

Oscillators Replacement Considerations

Direct substitutes must match the 37.125 MHz frequency, 1.8V supply, and 4-SMD package. Verify pinout compatibility and output logic levels. Check if the alternative component supports the same standby functionality and thermal range. Cross-reference mechanical dimensions to ensure board fit.
