18QHTF21-3.776-OE is listed in the Oscillators range at ChipApex. The manufacturer field lists Mercury Electronics Ind. Co. Ltd. Its product description is 3.776 MHz XO 1.8V 2.0X1.6 MM OE. Review the specifications below when checking this part for your BOM.
The 18QHTF21-3.776-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 3.776 MHz and utilizes LVCMOS output logic levels. The device is powered by a single 1.8V supply voltage and features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package suitable for surface-mount assembly. The component ensures frequency stability of ±50ppm and supports an operating temperature range from -40°C to 85°C.
Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm the exact enable/disable configuration and packaging variant. Ensure the 1.8V supply requirement aligns with the target system's voltage rails. Confirm that the ±50ppm stability meets the application's timing tolerance requirements before finalizing procurement orders.
Select this component when a low-voltage 1.8V operation is required alongside an enable/disable feature for power efficiency. The 3.776 MHz frequency is suitable for specific baud rate generation or reference clock applications. Consider the -40°C to 85°C industrial temperature range if the environment exceeds commercial limits. The small 4-SMD footprint aids in high-density PCB layouts.
This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'OE' suffix typically denotes specific operational characteristics such as enable/disable functionality. Mercury Electronics specializes in quartz crystals and timing devices, providing reliable frequency control solutions for global markets.
Direct substitutes must match the 3.776 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal specifications. Cross-reference with other manufacturers offering similar XO components with enable pins. Ensure the replacement maintains the ±50ppm stability and -40°C to 85°C temperature range.
