Procurement Notes
Verify component availability as distribution status may vary. Confirm package orientation and pin configuration against the official mechanical drawing before PCB layout finalization. Ensure storage conditions comply with moisture sensitivity level requirements to maintain device integrity during assembly processes.
Selection Notes
Select this component when a specific 303.825 MHz SAW resonator is required for SMD assembly. Consider the 8-pin footprint and 1.5mm height constraints for board space limitations. Validate thermal performance against the -40°C to +85°C operating range for the target environment.
Part Context
This part belongs to the Abracon ASR series of SAW resonators. It serves as a frequency-determining element in electronic circuits where stability and compactness are prioritized over the higher precision of quartz crystals. The series supports various standard RF frequencies for communication and timing applications.
Replacement Considerations
Direct substitutes include other 303.825 MHz SAW resonators in 8-SMD packages from compatible manufacturers. Verify electrical parameters and mechanical dimensions match exactly. Cross-reference with Abracon part number ASR303.825E for equivalent specifications.
