Overview
The 18QHTF21-10.130-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.13 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 reduce consumption. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.
Feature Summary
- Supports low-voltage operation at 1.8V
- Includes standby and power-down functionality
- Utilizes LVCMOS output logic
Applications
- Battery-powered devices
- Portable electronics
- General clock signal generation
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply rail matches the system design. Ensure the 4-SMD no-lead package footprint aligns with the PCB layout constraints. Check for RoHS compliance status if required by project specifications.
Selection Notes
Select this component when a small form factor is critical for the application. The 1.8V operating voltage makes it suitable for modern low-power digital circuits. Consider the LVCMOS interface compatibility with the target microcontroller or FPGA. Evaluate the need for the power-down feature to manage energy efficiency in portable designs.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a 2.0x1.6 mm package. The series is characterized by its low profile and suitability for high-density PCB layouts. Similar parts in the family include different frequency variants like 51.2 MHz or 8.0 MHz, sharing the same physical and electrical characteristics.
Replacement Considerations
Direct substitutes must match the 10.13 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and thermal performance. Cross-reference with other manufacturers offering similar ultra-small oscillators if Mercury stock is unavailable.
