18QHTF21-41.208-PD

Oscillators Overview

The 18QHTF21-41.208-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 41.208 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby or power-down function to manage energy consumption. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby and power-down functionality
• Provides LVCMOS output signal compatibility

Oscillators Applications

• General clock generation in electronic circuits
• Timing reference for digital systems
• Embedded devices requiring precise frequency control

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure that the 1.8V supply rail is stable and within the operational limits specified in the official datasheet. Confirm that the PCB footprint matches the 2.0x1.6mm SMD package dimensions to ensure proper assembly and electrical connection.

Oscillators Selection Notes

Select this component when a precise 41.208 MHz timing source is required for low-power applications. The choice is driven by the need for LVCMOS interface compatibility and the availability of a power-down mode. Consider the physical size constraints of the 2.0x1.6mm package when designing the layout. Evaluate thermal performance and stability needs relative to the operating temperature range defined by the manufacturer.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, a supplier specializing in quartz crystals and oscillators. The series typically offers various frequencies within a small form factor. Mercury Electronics has been active in the frequency-control industry since 1973, providing components such as TCXOs and VCTCXOs alongside standard XO products like this model.

Oscillators Replacement Considerations

Direct substitutes must match the 41.208 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify pinout compatibility and electrical characteristics with alternative manufacturers offering similar timing solutions.
