Aluminum Nitride Thin Film Precision Resistors Type RA73 Series Key Features High thermal conductivity Aluminum-Nitride substrate. High Power / Size ratio – Up to 1W in 0805 size. Thin film precision resistors with TCR to 25ppm and tolerances to 0.1%. Applications TE are pleased to introduce the new RA73 series. This is a high stability precision Thin Film chip resistor range offering very high power / size ratio – up to 1W in 0805 size. The RA73 series offers TCR down to 25ppm/°C and resistance tolerances to 0.1%. Standard values are within the IEC 63 E96 and E24 value grids. The RA73 resistors have accurate and uniform physical dimensions to facilitate automatic placement methods.
