Overview
The 18QHTF21-10.150-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.15 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features a power-down function for standby mode control. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm. The component is designed for applications requiring precise clock signals within specified operating temperature ranges.
Feature Summary
- Supports LVCMOS output logic for digital interface compatibility
- Includes power-down functionality to enable standby mode
- Utilizes quartz-based technology for frequency stability
Applications
- General purpose clock signal generation
- Digital circuit timing references
- Embedded system clock sources
Procurement Notes
Verify the exact specifications against the official manufacturer datasheet before procurement. Ensure the supply voltage matches the 1.8V requirement and confirm the package type aligns with PCB layout constraints. Check for any specific ordering suffixes that may alter electrical characteristics or packaging details.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. Consider the small 2.0x1.6mm footprint for space-constrained designs. Verify that the 10.15 MHz frequency meets the system timing requirements and that power-down capability is necessary for energy management.
Part Context
This part belongs to the Mercury Electronics SMD oscillator series, which includes various frequencies and package types. The 18QHTF21 series typically offers standard performance levels suitable for general electronic applications. Mercury Electronics has a long history in manufacturing frequency control products, including crystals and oscillators.
Replacement Considerations
Direct substitutes include other 10.15 MHz LVCMOS oscillators in similar packages from different manufacturers. Cross-reference pinouts and electrical parameters carefully. Alternative models within the same Mercury series may offer different frequencies but share similar form factors.
