18QHTF21-18.1818-OE

Oscillators Overview

The 18QHTF21-18.1818-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 18.1818 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, specifically supporting a supply voltage of 1.8V. It features an Enable/Disable control function, allowing for power management capabilities. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, suitable for miniaturized electronic designs.

Oscillators Feature Summary

• Compact 2.0x1.6 mm surface-mount package
• Low-voltage 1.8V operation
• LVCMOS output interface
• Enable/Disable control functionality

Oscillators Applications

• Miniaturized electronic circuit designs
• Portable consumer electronics
• Communication modules requiring precise timing
• Embedded systems with space constraints

Oscillators Procurement Notes

Verify the specific suffix (OE vs PD) to confirm control functionality. OE indicates Enable/Disable capability, while PD typically denotes Standby/Power Down. Ensure the 1.8V supply requirement aligns with system design. Confirm package dimensions match PCB footprint requirements. Request official datasheets for precise electrical characteristics before integration.

Oscillators Selection Notes

Select this model when a small form factor and low voltage operation are critical. The 18.1818 MHz frequency suits specific clocking needs. Consider the Enable/Disable feature for power-sensitive applications. Compare against similar Mercury series parts for alternative frequencies or packages. Validate thermal performance within the 2.0x1.6 mm footprint constraints.

Oscillators Part Context

This part belongs to the 18QHTF21 series of ultra-small crystal oscillators from Mercury Electronics. The series is characterized by its miniature 4-SMD no-lead package and low-voltage compatibility. It represents a solution for high-density PCB layouts where traditional oscillator packages are too large. The manufacturer emphasizes reliability and precision in frequency control products.

Oscillators Replacement Considerations

Direct substitutes may include other 18QHTF21 variants with different frequencies but identical pinouts and electrical specs. Verify that any replacement maintains the 1.8V supply and LVCMOS output type. Check if the control function (Enable/Disable) matches the original OE suffix requirement. Consult Mercury Electronics for cross-reference lists.
