Vishay Electro-Films
Thin Film Top-Contact Resistor
FEATURES
? Wire bondable
? Small size: 0.020 inches square
? Case: 0202
? Resistance range: 1.0 ? to 1 M ?
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.
? DC power rating: 250 mW
? Oxidized silicon substrate for good power dissipation
? Resistor material tantalum nitride, self passivating
? Moisture resistant
? Material categorization: For definitions of compliance

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.
