The TSFM series of single-value resistors chips offer a small
size, wide ohmic value range and excellent power capacity,
maintaining these qualities to temperatures up to 250 °C.
The TSFM Tantalum Nitride resistor material offers excellent
resistance to high moisture environments. The TSFMs are
manufactured using Vishay Electro-Films (EFI) sophisticated
thin-film equipment and manufacturing technology. The
TSFMs are 100 % electrically tested and visually inspected
to MIL-STD-883, method 2032 class H or K.
APPLICATIONS
Vishay EFI TSFM top-contact 0.02" square resistor chips
are designed to operate at elevated temperatures and
power loads in many types of hybrid (chip and wire)
assemblies. They are ideally suited for extreme environment
applications such as “down hole” drilling.
