BetaTherm Thermistor Series IV provides a higher
Dissipation Constant (3.0mW/oC) allowing design
engineers greater flexibility on sensor design projects. The
higher D.C. is achieved using 28 AWG tin plated copper
lead wires and also larger chip thermistor elements. These
chip elements are manufactured using the same high quality
materials and manufacturing process as Series I. Custom
resistance values and tolerances are available upon request.
