SFM

Vishay Electro-Films

Thin Film Top-Contact Resistor

FEATURES

• Wire bondable

Product may not

be to scale

• Small size: 0.020 inches square

• Resistance range: 1.0 Ω to 1 MΩ

• DC power rating: 250 mW

• Oxidized silicon substrate for good power dissipation

• Resistor material tantalum nitride, self passivating

• Moisture resistant

The SFM series single-value resistor chips offer a small size,

wide ohmic value range and excellent power capacity.

The SFMs tantalum nitride resistor material offers excellent

resistance to high moisture environments.

The SFMs are manufactured using Vishay Electro-Films

(EFI) sophisticated thin film equipment and manufacturing

technology. The SFMs are 100 % electrically tested and

visually inspected to MIL-STD-883.

APPLICATIONS

Vishay EFI SFM 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.
