RFID, RF Access, Monitoring ICS Procurement Notes

Verify that the specific suffix DF403C+ matches the required pinout and electrical characteristics for your design. Confirm the die package requirements and handling procedures for bare die components. Ensure compatibility with the intended reader hardware for the 100kHz-150kHz band. Check for any specific environmental ratings if deployed in harsh conditions.

RFID, RF Access, Monitoring ICS Selection Notes

Select this component when ISO 11784/11785 compliance is mandatory for animal identification. Consider the 512-bit memory capacity against application data needs. Evaluate the die form factor for custom module assembly versus pre-packaged alternatives. Verify operational temperature ranges if used in extreme environments.

RFID, RF Access, Monitoring ICS Part Context

This part belongs to the EM4305 series from EM Microelectronic, specialized in ultra-low power RFID solutions. It complements other EM products like the EM4035 and EM4205, targeting different frequency bands and protocol standards.
