Overview
The 18QHTF21-118.000-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind., Co., Ltd. It operates at a fixed frequency of 118.0 MHz and utilizes LVCMOS output logic. The device functions on a 1.8V supply voltage and features a standby power-down mode for energy efficiency. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.
Feature Summary
- Supports low-power standby operation via power-down functionality
- Utilizes LVCMOS output logic for digital interface compatibility
- Designed for battery-powered applications due to low current consumption
Applications
- Battery-powered portable devices
- Portable electronic equipment
- Digital signal processing circuits
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 2.0x1.6mm footprint matches your PCB layout constraints. Check for any specific manufacturing date codes or lot traceability requirements if applicable to your quality standards.
Selection Notes
Select this component when a precise 118.0 MHz clock signal is required in space-constrained designs. The 1.8V operating voltage makes it suitable for modern low-voltage digital systems. Consider the low maximum supply current of 26mA for power-sensitive applications. The SMD no-lead package facilitates automated surface-mount assembly processes.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in frequency control products. The series includes various frequencies and package sizes, such as the 3.2x2.5mm variants. Mercury Electronic has been a pioneer in the crystal industry since 1973, providing reliable oscillators for global electronics markets.
Replacement Considerations
Direct substitutes within the same series include other frequencies like 18QHTF21-96.768-PD or 18QHTF21-8.000-PD, provided the frequency difference is acceptable. Cross-model replacements from other manufacturers require careful verification of pinout, voltage, and size compatibility.
