SFN www.vishay.com Vishay Electro-Films NiCr Thin Film, Top-Contact Resistor FEATURES • Wire bondable • Chip size: 0.020" square • Case: 0202 • Resistance range: 10 to 510 k • Resistor material: Nichrome • Oxidized silicon substrate Product may not be to scale • 125 mW power The SFN series resistor chips offer a combination of nichrome stability, good power rating and small size. The SFNs are manufactured using Vishay Electro-Films (EFI) sophisticated thin film equipment and manufacturing technology. The SFNs are 100 % electrically tested and visually inspected to MIL-STD-883, method 2032, class H or class K. • Material categorization: for definitions of compliance please see www.vishay.com/doc?99912 APPLICATIONS Vishay EFI SFN resistor chips are widely used in hybrid packages where space is limited. Designed with capacity to handle substantial power loads, they also have the benefit of nichrome stability. Recommended for hermetic environments where die is not exposed to moisture.
