3 / 16 page 1998 Mar 26 3 Philips Semiconductors Product specification Silicon temperature sensors KTY81-2 series LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 134). CHARACTERISTICS Tamb =25 °C, in liquid, unless otherwise specified. Notes 1. The thermal time constant is the time taken for the sensor to reach 63.2% of the total temperature difference. For example, if a sensor with a temperature of 25 °C is moved to an environment with an ambient temperature of 100 °C, the time for the sensor to reach a temperature of 72.4 °C is the thermal time constant. 2. Inert liquid, e.g. FC43 manufactured by the 3M company. SYMBOL PARAMETER CONDITIONS MIN. MAX. UNIT Icont continuous sensor current in free air; Tamb =25 °C − 10 mA in free air; Tamb = 150 °C − 2mA Tamb ambient operating temperature −55 +150 °C SYMBOL PARAMETER CONDITIONS MIN. TYP. MAX. UNIT R25 sensor resistance Icont =1mA KTY81-210 1980 − 2020 Ω KTY81-220 1960 − 2040 Ω KTY81-221 1960 − 2000 Ω KTY81-222 2000 − 2040 Ω KTY81-250 1900 − 2100 Ω KTY81-251 1900 − 2000 Ω KTY81-252 2000 − 2100 Ω TC temperature coefficient − 0.79 − %/K R100/R25 resistance ratio Tamb = 100 °C and 25 °C 1.676 1.696 1.716 R−55/R25 resistance ratio Tamb = −55 °C and 25 °C 0.480 0.490 0.500 τ thermal time constant; note 1 in still air − 30 − s in still liquid; note 2 − 5 − s in flowing liquid; note 2 − 3 − s rated temperature range −55 − +150 °C |
