Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your design specifications before procurement. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm the 4-SMD package footprint matches your PCB layout constraints. Request the official datasheet from Mercury Electronics for detailed electrical characteristics and reliability data.

Oscillators Selection Notes

Select this component when a low-profile, low-voltage oscillator with power-down capability is required. The 27.02 MHz frequency is specific; ensure it matches the target system clock needs. Consider the LVCMOS interface compatibility with downstream logic. The small form factor makes it ideal for space-constrained designs. Verify availability of the PD suffix variant if power management is critical.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within a standardized 2.0x1.6mm package. The 'PD' suffix indicates the inclusion of a power-down control feature.
