Rolling Meadows, Ill. Ohmite Manufacturing Company said the TFS series thick-film resistors absorb much more energy compared to standard film resistors, making them suitable for medical surge protection applications.
Available in six standard sizes, these flat, axial-leaded devices are available with power ratings of 0.5 watts to 2 watts and energy ratings from 6 to 55 joules for a single impulse. These non-inductive devices offer a resistance range from 100 to 100,000 ohms with a tolerance as low as1% and a temperature of coefficient resistance (TCR) of 100 ppm. Operating voltages range from 3 kV to 11kV.
Other applications for these RoHS-compliant resistors include power supply conversions, electron microscopes, X-ray systems, high-resolution CRT displays, and geophysical instrument-related products.
Pricing ranges from $1.22 to $2.11 each in quantities of 1,000.
