ESCC 4001/025 ( ) Qualified High Precision  
Thin Film Chip Resistor Arrays  
FEATURES  
• Thin film technology  
• 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 (3 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  
• ESA/ESCC qualified  
• ESCC 4001 (generic specification)  
• ESCC 4001/025 (detailed specification)  
• SMD wraparound chip resistor array  
• Up to eight different ohmic values (CNW HR)  
• Suitable for military use  
Vishay Sfernice Thin Film division holds ESCC QML  
qualification (ESCC technology flow qualification). PRA  
Hi-Rel arrays can be used in most applications requiring a  
matched pair (or set) of resistor elements. The networks  
provide 3 ppm/°C TCR tracking, a ratio tolerance as tight as  
0.05 % and outstanding stability. They are available in  
1 mm, 1.35, mm and 1.82 mm pitch.  
• Material categorization: for definitions of compliance
