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 pitch:
• 0.70 mm for PRA073 (based on case 0302)
• 0.70 mm for PRA074 (based on case 0402)
• 1.00 mm for PRA100 (based on case 0603)
• 1.35 mm for PRA135 (based on case 0805)
• 1.82 mm for PRA182 (based on case 1206)
