RF Receivers Procurement Notes

Verify the specific datasheet version and RoHS compliance status prior to procurement, as manufacturing changes may occur. Confirm that the 16-SMD castellated package footprint matches your PCB design requirements. Ensure the supply voltage range of 2.1 V to 3.6 V aligns with your system's power architecture. Check for any recent product change notices regarding marking or material composition updates.

RF Receivers Selection Notes

Select this module when high sensitivity (-112 dBm) is required for extended range communication at 433 MHz. It is suitable for low-data-rate applications up to 10 kbps using ASK or OOK modulation. Consider the 16-SMD surface-mount form factor for space-constrained designs. Ensure the operating temperature range of -40°C to +70°C meets environmental conditions. Compare against other LR series variants if different frequency bands or pin configurations are needed.
