Resonators Procurement Notes

Verify the specific suffix 'MD' against the official Abracon datasheet to confirm the exact tolerance and packaging configuration. Ensure that the through-hole footprint matches the PCB layout requirements, specifically the 5 mm lead spacing. Confirm RoHS compliance status directly from the manufacturer's documentation prior to procurement.

Resonators Selection Notes

Select this component when a cost-effective, through-hole solution is required for 4 MHz timing applications. It serves as an alternative to quartz crystals where slightly lower stability is acceptable. Consider the 30 Ohm ESR and 36 pF internal capacitance when designing the oscillator circuit to ensure proper startup and operation.

Resonators Part Context

This part belongs to the Abracon HWZT series of washable ceramic resonators.
