18QHTF21-41.000-PD

Oscillators Overview

The 18QHTF21-41.000-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 41.000 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a Standby (Power Down) control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.

Oscillators Feature Summary

• Supports Low Voltage CMOS (LVCMOS) output logic levels
• Includes standby mode capability for power management
• Utilizes surface-mount technology for automated assembly

Oscillators Applications

• General-purpose timing circuits
• Embedded systems requiring precise clock signals
• Consumer electronics devices

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any RoHS compliance documentation if required for your manufacturing standards.

Oscillators Selection Notes

Select this component when a low-voltage, small-footprint oscillator is required for digital logic interfaces. The LVCMOS output ensures compatibility with standard microcontrollers and FPGAs operating at 1.8V. Consider the standby feature if power efficiency during idle periods is a critical design parameter. Verify thermal performance within the specified operating temperature range.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a 2.0x1.6mm SMD package. The series supports both 1.8V and 2.5V operation options across different model variants. The 'PD' suffix indicates the inclusion of a power-down pin functionality, distinguishing it from non-standby versions.

Oscillators Replacement Considerations

Direct substitutes include other 41.000 MHz LVCMOS oscillators in 2.0x1.6mm packages from manufacturers such as Epson or SiTime. Ensure replacement parts match the 1.8V supply requirement and LVCMOS output characteristics. Verify that the pinout configuration is identical to avoid PCB redesign.
