SFM Vishay Electro-Films CHIP RESISTORS Thin Film Top-Contact Resistor FEATURES * Wire bondable Product may not be to scale * Small size: 0.020 inches square * Resistance range: 1.0 to 1 M * DC power rating: 250 mW 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. * Oxidized silicon substrate for good power dissipation * Resistor material tantalum nitride, self passivating * Moisture resistant 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.
