to 1 MΩ
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.
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.
Quartz substrate: < 0.1 pF shunt capacitance
Resistor material: Tantalum nitride, self passivating
Moisture resistant
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.
