Moisture resistant
The SFP series single-value resistor chips offer a small size,
wide ohmic value range and excellent power capacity.
The SFPs are part marked with resistance value allowing
user the ability to visually determine the resistance value of
the chip.
The SFPs are manufactured using Vishay Electro-Films
(EFI) sophisticated thin film equipment and manufacturing
technology.
The SFPs are 100 % electrically tested and visually
inspected to MIL-STD-883.
APPLICATIONS
Vishay EFI SFP small resistor chips are widely used in hybrid packages where space is limited and chip value marking is
important for identification. The die is part marked with the resistance value. Wire bonding is made to the two pads on the top of
the chip.
