Procurement Notes
Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm exact electrical characteristics and pinout configuration. Ensure the operating temperature range meets system requirements. Cross-reference the part number with authorized distributors to avoid counterfeit components. Confirm that the 1.8V supply voltage aligns with the target circuit design before procurement.
Selection Notes
Select this component when a 13.43 MHz clock source is required for LVCMOS interfaces. Consider the 1.8V supply constraint and the need for enable/disable control. Evaluate the 2.0x1.6mm footprint against available PCB space. Compare performance against other Mercury oscillators if different frequencies or packages are needed.
Part Context
Mercury Electronics Ind. Co. Ltd specializes in frequency control products including quartz crystals and oscillators. The 18QHT series represents their SMD oscillator lineup. This model fits within their portfolio of timing solutions for consumer and industrial electronics. The company has decades of experience in Taiwan's quartz industry.
Replacement Considerations
Check for direct substitutes from Mercury Electronics with identical frequency and package. Verify compatibility with other manufacturers offering 13.43 MHz LVCMOS oscillators in 4-SMD No Lead packages. Ensure electrical parameters match exactly before substitution.
