Resistor Pastes
FK9600, FK9900M-100 and FK9900M-200 resistor paste systems were developed for use on AlN substrates. This allows to produce high-precision thick-film resistors onto AlN for use in power electronics.
FK9600
The RuO2-based FK9600 resistor paste system, with sheet resistance values of 6 to 6,000 Ohm/Sq, is compatible with the conductor pastes FK1205, FK1916 and FK1953, as well as with the encapsulation paste FK4027. Other pastes can be used as conductor paste, but this may result in differing sheet resistance values or temperature coefficients. The pastes of the FK9600 paste system in the table below can be mixed with each other as needed. We do not recommend mixing with the resistor pastes of the FK9900M series.
