QFM Vishay Electro-Films CHIP RESISTORS Thin Film, Top-Contact Resistor FEATURES Product may not be to scale * Wire bondable * Small size, 0.020 inches square * Resistance range: 1.0 to 1 M * DC power rating: 25 mW The QFM series tantulum nitride on quartz single-value resistor chips offer a small size, wide ohmic value range and excellent frequency response. The QFMs tantalum nitride resistor material offers excellent resistance to high moisture environments. * Quartz substrate: < 0.1 pF shunt capacitance * Resistor material: Tantalum nitride, self passivating * Moisture resistant The QFMs are manufactured using Vishay Electro-Films (EFI) sophisticated thin film equipment and manufacturing technology. The QFMs are 100 % electrically tested and visually inspected to MIL-STD-883. APPLICATIONS The QFM 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.
