Thick Film Resistors & Thermistors By Koartan
Koartan offers a complete range of resistor, NTC & PTC-thermistors blendable inks with resistivities from 50 milli-Ohms per square up to 1 Giga-Ohms per square, depending on the application. Base materials include Silver Palladium and Ruthenium Oxide.
The 79XX series of Silver Palladium resistors are suitable for fabrication of high powered chip & network resistors, high voltage surge protection in telecomms applications, are BeO compatible, and offer a tight TCR.
The 732X series are suitable for fabrication of discrete surface mount components, for integrating temperature sensing, impedance matching, current limiting or switching sub-circuitry, with large Beta constant & small hysteresis.
The 738X series offers a stacked NTC thermistor system designed to greatly enhance temperature sensitivity over standard “planar” systems. It also allows passive incremental laser trimming, providing electrical conduction through the thermistor in the Z direction.
