SFP Vishay Electro-Films CHIP RESISTORS Thin Film Top-Contact Resistor with Part Mark FEATURES * Wire bondable Product may not be to scale 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. * Part marked - 5 digits * Small size: 0.022 inches square * Resistance range: 1 to 1 M * DC power rating: 250 mW * Oxidized silicon substrate for good power dissipation * Resistor material: Tantalum nitride, self passivating * Moisture resistant 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.
