Vishay Electro-Films
Thin Film, Top-Contact Resistor
Product may not be to scale
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, method 2032 class H
or K.

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.
