18QHTF21-62.300-PD

Overview

The 18QHTF21-62.300-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 62.300 MHz with an LVCMOS output interface. The device supports a supply voltage of 1.8V and features a standby power-down mode. It is housed in a compact 4-SMD, No Lead package. The unit offers frequency stability of ±50ppm and functions within an operating temperature range of -40°C to 85°C. Maximum supply current is rated at 24mA.

Feature Summary

• Supports low-voltage operation at 1.8V with integrated standby capability
• Provides precise timing via LVCMOS output signals
• Engineered for surface-mount assembly in space-constrained designs

Applications

• Consumer electronics requiring precise clock synchronization
• Industrial control systems operating in varied thermal environments
• Communication equipment utilizing standard logic interfaces

Procurement Notes

Verify the specific suffix 'PD' against official Mercury Electronics documentation to confirm the presence of the power-down feature. Ensure the requested frequency matches exactly 62.300 MHz, as minor variations exist within the series. Confirm that the 4-SMD no-lead footprint aligns with your PCB layout requirements before finalizing orders.

Selection Notes

Select this component when a 1.8V supply constraint exists alongside the need for a standby mode. The ±50ppm stability suits general-purpose applications rather than high-precision metrology. Consider the 4-pin form factor for density needs, but verify thermal dissipation capabilities within the -40°C to 85°C operational window for your specific enclosure design.

Part Context

Mercury Electronic Industrial Co., Ltd. specializes in frequency control products including quartz crystals and oscillators. This model belongs to their standard XO line, designed for reliable timing in commercial and industrial sectors. The manufacturer has decades of experience in Taiwan's quartz industry, focusing on precision timing solutions.

Replacement Considerations

Cross-reference part numbers like 18QHTF21-62.300-OE or similar variants from Mercury Electronics for potential substitutes. Verify that any replacement maintains the identical 4-SMD package and 1.8V LVCMOS specifications to ensure mechanical and electrical compatibility without redesigning the host circuit.
