Ω
to 510 kΩ
Resistor material: Nichrome
Oxidized silicon substrate
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.
250 mW power
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.
