SFN Vishay Electro-Films CHIP RESISTORS NiCr Thin Film, Top-Contact Resistor FEATURES * Wire bondable * Chip size: 20 inches square Product may not be to scale * Resistance range: 10 to 510 k * Resistor material: Nichrome * Oxidized silicon substrate The SFN series resistor chips offer a combination of nichrome stability, good power rating and small size. * 250 mW power 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. 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.
