Resistance range: 1.0
Ω
to 1 MΩ
DC power rating: 250 mW
Oxidized silicon substrate for good power dissipation
Resistor material tantalum nitride, self passivating
Moisture resistant
The SFM series single-value resistor chips offer a small size,
wide ohmic value range and excellent power capacity.
The SFMs tantalum nitride resistor material offers excellent
resistance to high moisture environments.
The SFMs are manufactured using Vishay Electro-Films
(EFI) sophisticated thin film equipment and manufacturing
technology. The SFMs are 100 % electrically tested and
visually inspected to MIL-STD-883.
APPLICATIONS
Vishay EFI SFM top-contact resistor chips are designed to handle substantial power loads in many types of hybrid packages.
They are ideally suited for this purpose because of their small size.
