Electrical characteristics Symbol Parameter Condition Min Typ Max Unit H_ISO Operating field according to ISO TA = 0 °C to 50 °C 1500 - 7500 mA/m H_extended Operating field in extended temperature range TA = -40 °C to 85 °C 1500 - 7500 VRET Back-scattering induced voltage ISO 10373-6 20 - - mV CTUN Internal tuning capacitor 13.56 MHz (1) 62 68 74 pF 1. The tuning capacitance value is evaluated by characterization with equipement at chip power on reset and ambient temperature. This value is to be used as reference for antenna design. Min and max value are deduced from correlation at ambient temperature with industrial tester limits. Note: For inlay implementation, the antenna design applied for SRI2K can be re-used as-is for ST25TB02K: typical 68pF value for the ST25TB02K is equivalent to what was specified in the SRI2K data-sheet as 64pF. This change is related to a different measurement methodology between SRI2K and ST25TB02K. Table 14.
