NiCr Thin Film, Top-Contact Resistor
Product may not be to scale
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.
FEATURES
• Wire bondable
• Chip size: 20 inches square
• Case: 0202
• Resistance range: 10  to 510 k
• Resistor material: Nichrome
• Oxidized silicon substrate
• 125 mW power
• Material categorization: For definitions of compliance

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.
