• Industrial control modules

Oscillators Procurement Notes

Verify the specific ordering suffix PD against official Mercury Electronics documentation to confirm the standby function and package type. Ensure the required frequency tolerance of ±50ppm aligns with system requirements. Confirm the 1.8V supply voltage matches the target circuit design before procurement.

Oscillators Selection Notes

Select this component when a low-profile surface mount oscillator is required for 1.8V logic interfaces. The choice depends on the necessity for a standby feature to reduce power consumption during idle periods. Verify that the 4-SMD footprint fits the available PCB space and that the thermal range meets environmental conditions.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and output types in a standardized small form factor. The PD suffix typically indicates specific pin configurations or functional options like standby support within this product line.

Oscillators Replacement Considerations

Direct substitutes must match the 29.1475 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD package dimensions. Cross-reference with other manufacturers offering similar low-profile oscillators with identical electrical specifications and pinouts.
