Procurement Notes

Verify component authenticity through authorized channels due to potential supply chain variations. Confirm mechanical fit within the target enclosure, specifically the 45x36x19.5 mm dimensions and flange mounting requirements. Ensure electrical compatibility with the driving circuit regarding the 8 Ohm impedance load. Check operational temperature limits against the intended environment, as the specified range is -20 C to +60 C. Validate that wire lead termination matches the assembly process.

Selection Notes

Select this model when a rectangular footprint is required for space-constrained designs. Choose based on the specific need for an 8 Ohm impedance matching standard audio drivers. Consider the 88 dBA sensitivity for volume requirements in small enclosures. Evaluate the Mylar cone properties for cost-effective acoustic performance. Ensure the operating temperature range aligns with the deployment environment constraints.
