PRA 100, 135, 182 (CNW) Vishay Sfernice High Precision Resistor Chip Arrays FEATURES PRA arrays can be used in most applications requiring a matched pair (or set) of resistor elements. The networks provide 1 ppm/C TCR tracking, a ratio tolerance as tight as 0.01 % and outstanding stability. They are available in 1 mm, 1.35 mm and 1.82 mm pitch. * 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) * Pre-tinned terminations over nickel barrier * High temperature option (200 C) * SMD wraparound chip resistor array * Compliant to RoHS directive 2002/95/EC TYPICAL PERFORMANCE ABS TRACKING TCR 10 ppm/C 2 ppm/C ABS RATIO TOL 0.1 % 0.05 % DIMENSIONS Suggested Land Pattern I: Independent resistors R Electrical diagram R1 R2 R7 R8 Termination E S R P DIM.

Please refer to application note "Power Dissipation High Temperature SCH" www.vishay.com/doc?53047 for recommendations and mounting considerations. Operating temperature range: - 55 C; + 200 C Minimum ohmic value: 250 Tooling charges might be required for custom networks series (definitive set of masks). MECHANICAL SPECIFICATIONS Substrate Alumina Technology Thin Film Film Absolute TCR: 10 ppm/C typical (maximum 15 ppm/C) Nickel chromium with mineral passivation B type: SnPb over nickel barrier Terminations TCR tracking: 2 ppm/C typical (maximum 5 ppm/C) N type: SnAg over nickel barrier G type: Gold over nickel barrier Load life stability at 200 C: < 0.1 % at 0.1 Pn after 1000 h QUICK PROTOTYPING SPECIAL FEATURES Vishay Sfernice can offer quick prototyping service in 3 weeks production time for standard and custom networks (independent resistors - For networks with common point lead time might be longer). (Logistics time to add to this lead time). No NRE require for prototyping (small quantity). 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.
