The TFS Series has been specifically 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 noninductive performance in an axial package. Uses include power supply conversion, electron microscopes, X-ray systems, highresolution CRT displays, and geophysical instrument related products.

Always verify designs with pulse and surge conditions through thorough testing of the design at maximum operating temperature and maximum pulse loading (or some margin 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.
