General Characteristics
INTRODUCTION
thermistors thermally sensitive resistors made from mixture oxides. Sintered ceramic bodies various sizes obtained. Strict conditions mixing, pressing, sintering metallization ensure excellent batch-to-batch product characteristics. This semi-conducting material reacts resistor, whose resistance decreases with increasing temperature.

DESIGN THERMISTOR
Choice resistances
application measure temperature around defined point, unique nominal resistance chosen (for example, among standard values range products presented pages 21). When required measure temperature over selected ranges corresponding resistance must such that they located characteristic existing material (for example among standard materials whose displayed pages 35). resistances must also compatible with resistivity material dimensions thermistor.
Choice tolerances
precision temperature measurement determines calculation tolerance resistance: (%/°C). (°C) example, NR55-3049-99, using "N5" material characteristic displayed page 34), requires precision over temperature range 110°C 120°C. tolerances calculated: R110°C /R110°C 1°C* 2.91%/°C 2.91% R120°C /R120°C 1°C* 2.76%/°C 2.76% *For your specific requirements, please consult
