18QHTF21-6.0052-OE

Overview

The 18QHTF21-6.0052-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 6.0052 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features enable/disable functionality for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. The unit supports a frequency stability of ±50ppm and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrated enable and disable control mechanism for efficient power management
• Compact surface-mount design suitable for space-constrained PCB layouts
• LVCMOS output interface compatible with standard digital logic circuits

Applications

• General purpose clock generation for embedded systems
• Timing reference for consumer electronic devices
• Clock source for portable communication equipment

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. 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 guidelines. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure reliable assembly and long-term performance.

Selection Notes

Select this component when a low-voltage, small-footprint oscillator is required for timing applications. Consider the ±50ppm stability specification to ensure it meets your system's jitter and accuracy requirements. Evaluate the enable/disable feature if power conservation is critical for the end product. Compare the physical dimensions against available board space to confirm compatibility with the design constraints.

Part Context

This part belongs to the Mercury Electronic Ind. Co. Ltd. family of quartz crystal oscillators. The company specializes in frequency control products including crystals, filters, and various oscillator types.
