High-Precision Thin Film Chip Resistor Arrays, Sulfur Resistant

Applications

• High-stability passivated nichrome resistive layer 0.02 % on ratio, 1000 h at Pn at +70 °C
• Tight TCR (10 ppm/°C) and TCR tracking (to 1 ppm/°C)
• Very low noise < -35 dB and voltage coefficient < 0.01 ppm/V
• Ratio tolerance to 0.01 % (R ≥ 200R)
• High-temperature (230 °C) version, see PRA HT
• ESA-qualified version, see PRA HR
• SMD wraparound chip resistor array
• Thin film technology
• Option to withstand humidity test of AEC-Q200
• Sulfur resistant (per ASTM B809-95 humid vapor test)
• Resistance values can be different on a given network (R max./R min. as high as 300). Tooling charges might be required depending on the ohmic values in the same network. Please, consult Vishay Sfernice for ohmic values, tolerances and also temperature coefficient (e.g. ± 1 ppm/°C) outside the standard range.
