18QHTF21-2.450-OE

Oscillators Overview

The 18QHTF21-2.450-OE is a 2.45 MHz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates on a 1.8V supply voltage and features an LVCMOS output signal. The device includes an Enable/Disable function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. The unit supports an operating temperature range of -40°C to 85°C and maintains frequency stability within ±50ppm.

Oscillators Feature Summary

• Compact 2.0x1.6 mm surface-mount package design
• Low voltage 1.8V operation capability
• Integrated enable/disable control functionality

Oscillators Applications

• Portable consumer electronics requiring low power consumption
• Mobile communication devices
• Embedded systems with limited space constraints

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply rail is stable to maintain the specified ±50ppm frequency stability. Confirm that the PCB footprint matches the 4-SMD no-lead package dimensions of 2.0x1.6 mm to avoid assembly issues during manufacturing.

Oscillators Selection Notes

Select this component when a small form factor and low voltage operation are critical. The LVCMOS output is suitable for direct interfacing with standard digital logic. Consider the ±50ppm stability if precise timing is required over the full industrial temperature range. The enable pin allows for dynamic power saving in battery-operated applications.

Oscillators Part Context

This part belongs to the 18QHTF21 series of high-frequency oscillators from Mercury Electronics. The series typically offers various frequencies and package sizes. This specific model focuses on ultra-small footprint applications while maintaining standard LVCMOS compatibility. It complements larger packages like the 7.0x5.0mm variants in the same family.

Oscillators Replacement Considerations

Direct replacements must match the 2.45MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify that substitute parts support the same ±50ppm stability and -40°C to 85°C temperature range. Check for identical enable/disable pin configurations to ensure board compatibility without redesign.
