Vishay Electro-Films

Thin Film, Top-Contact Resistor

FEATURES

• Wire bondable

• Small size: 0.020 inches square

• Case: 0202

• Resistance range: 1.0



to 1 M

Product may not be to scale

• DC power rating: 25 mW

• 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.

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.
