ZNI1000TA

ZNI1000 Temperature sensor Description The ZNI1000 is a Ni thin film Resistance Temperature Detector (RTD), specified to DIN 43760. The high temperature coefficient offers higher signal outputs than other RTD's, which results in higher accuracy with smaller temperature changes. Features • Resistance at 0°C: 1000 • Nickel temperature detector • Specified to DIN 43760 • SOT23 package Applications • Automotive electronic • Circuit protection • Temperature compensation • Temperature measurement Ordering information 1 Device Reel size (inches) Tape width (mm) Quantity per reel Device marking ZNI1000TA 7 8 3,000 ZNI ZNI1000TC 13 8 10,000 ZNI 3 2 Pinout - top view Pin 1 - Ni1000 Pin 2 - Ni1000 Pin 3 - Need a good thermal contact for short response time Issue 5 - June 2007 © Zetex Semiconductors plc 2007 1 www.zetex.com ZNI1000 Absolute maximum ratings Parameter Limit Unit ICC 5 mA Total power dissipation PTOT 20 mW Operating temperature range TA -55 to +150 °C Storage temperature range Tstg -55 to +150 °C Continuous Symbol current(a) NOTES: (a) Limited by operating temperature [ ICCⱕ(20mW/R)½ , R=func(TA)=718 to 1986⍀].
