TFSA100RFE Datasheet, PDF (1/1 Pages) Ohmite Mfg. Co. – Surge Capable Thick Film Non Inductive

The TFS Series has been spe-
cifically developed to absorb
large amounts of energy by
efficient use of its compact
mass. Ideal for medical surge
protection applications, these
thick film reisistors offer non-
inductive performance in an
axial package.
Uses include power supply
conversion, electron micro-
scopes, X-ray systems, high-
resolution CRT displays, and
geophysical instrument related
products.
FEATURES
• Appropriate for medical surge
protection applications
• Ideal to replace standard carbon
composition resistors
• Custom dimensions, values,
tolerances and characteristics

*Published energy rating is for 10ms pulse. For shorter pulses energy rating has to be
derated according to Max. Individual Pulse Rating chart (left) and Single Pulse Energy
Rating considerations (see ohmite.com).

NOTES
• Momentary overload capability is 5 times rated power for
1 second or 2 times rated power for 5 seconds. Always
verify designs with pulse and surge conditions through
thorough testing of the design at maximum operating
temperature and maximum pulse loading (or some mar-
gin above maximum pulse loading).
• Damage to the resistor by excessive pulse loading is
generally indicated by an increasing resistance of the
resistor.
• Energy ratings are based on single pulses (at least 1
minute between pulses).
• For multiple pulse applications the energy pulse rating
should be reduced and the average power should not
exceed the nominal power rating of the selected model.
