FEATURES
•Solderable wraparound terminations
•Alumina substrate base with PTC thick film element
•0603, 0805, and 1206 sizes available
•Available in tape and reel packaging
•Standard tolerances: ± 5 %, ± 10 %
•Contact factory for non-standard tolerance
•Linear from - 55 °C to + 125 °C
•Maximum linear deviation: ± 0.01 %/°C
Notes 1. Contact Vishay Dale if closer TCR lot tolerance is desired. 2. Other R25 values and tolerances are available upon request.
Note
1. Rated Continuous Working Voltage is maximum working voltage or square root of the power rating times resistance value, whichever is less.
