Procurement Notes

Verify current availability status directly with Abracon or authorized distributors, as electronic components may undergo lifecycle changes. Confirm that the specific order matches the RoHS compliance requirements and the exact pin configuration documented in the official datasheet. Ensure storage conditions adhere to moisture sensitivity level guidelines to maintain component integrity prior to soldering.

Selection Notes

Select this component when designing circuits requiring precise frequency reference in the 433.92 MHz range. Consider the 50-ohm resonant impedance and 2.2 pF load capacitance for matching network design. Evaluate the -40°C to +85°C operating range against environmental conditions. Compare physical dimensions against available board space to ensure compatibility with the 8-pin SMD package.

Part Context

This part belongs to the Abracon ASR series of SAW resonators, which are engineered for RF applications. Unlike standard crystals, SAW resonators offer robust performance in high-frequency ISM bands. The ASR433.92E-T specifically targets industrial and consumer electronics requiring reliable sub-GHz communication frequencies with minimal phase noise and stable oscillation characteristics.
