ZERO POWER THE ZERO POWER RESISTANCE IS SEE RATING RESISTANCE THE RESISTANCE OF A THERMISTOR TABLE AT 25¡É AMBIENT TEMPERATURE. B VALUE B VALUE CAN BE DERIVED BY SEE RATING MEASURING THE RESISTANCE AT TABLE 25¡É (R1) AND85¡É (R2) AND CALCULATING BY FOLLOWING FORMULA. Ln(R2/R1) MAX. STEADY THE MAX STEADY STATE CURRENT IS SEE RATING STATE CURRENT THE MAXIMUM ALLOWABLE CURRENT TABLE AT LOADING TO MAX OPERATING TEMPERATURE IN 25¡É AMBIENT. THERMAL THE DISSIPATION CONSTANT MEANS SEE RATING DISSIPATION THE AMOUNT OF POWER REQUIRED TABLE CONSTANT TO RAISE THE APPLIED TEMPERA- TURE TO THE THERMISTOR IN STATIONARY STATE FOR 1¡É. THERMAL TIME THE TIME CONSTANT IS DEFINED AS SEE RATING CONSTANT RELATIONSHIP BETWEEN THE THERMAL TABLE CAPACITY AND DISSIPATION CONSTANT. IT IS MEASURED AS TIME IN SECONDS WITCH IS NEEDED FOR THERMISTOR TEMPERATURE CHANGE DF 63.2% DIFFERENCE BETWEEN INITIAL AND FINAL THERMISTOR TEMPERATURE. TECHNICAL TERMS DESCRIPTIONS SPEC. - 3 -
