Vishay Electro-Films
Thin Film Top-Contact Resistor
Product may not be to scale
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.
FEATURES

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.
