Thin Film, Top-Contact Resistor  
FEATURES  
• Wire bondable  
• Small size: 0.020 inches square  
• Case: 0202  
• Resistance range: 1.0 to 1 M  
• DC power rating: 25 mW  
Product may not be to scale  
• Quartz substrate: < 0.1 pF shunt capacitance  
• Resistor material: Tantalum nitride, self passivating  
• Moisture resistant  
The QFM series tantulum nitride on quartz single-value  
resistor chips offer a small size, wide ohmic value range and  
excellent frequency response.  
• Material categorization: For definitions of compliance  
please see www.vishay.com/doc?99912  
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.
