Michael Comberiate, who manages the Special Projects Initiatives at the NASA/Goddard Space Flight Center, and his team of graduate and undergraduate engineering students build robotic vehicles that are used to test flight avionics, instruments, communications protocols, and approaches for planetary exploration. One project involves developing new communication protocols suitable for the delays encountered in space…
Resistors Deliver Precise Heating Control
Certain medical equipment requires “instant on/instant off” temperature control. IRC has developed a series of thick film planar resistive heating elements on insulated stainless steel substrates that deliver such a feature. Based on Thick Film on Steel technology (WDBR), the heating elements replace conventional heaters with an intrinsically safe, flameproof planar device that can be…
MINI Analog Shunt Transducer from Phoenix Contact
MIDDLETOWN, PA ‚– The new MINI Analog Shunt Transducer from Phoenix Contact is ideal for converting and isolating mV signals from shunt resistors. The new transducer features three-way 1.5 kV isolation, low power consumption and high-quality signal transmission. Current shunt resistors are precision resistors used in the measurement of DC electrical currents by creating a…
Metal Oxide Resistors
CMO Series commercial grade metal oxide resistors come in both standard and miniature sizes, with power ratings from 0.25 W to 9 W at 70° C, and a maximum operating temperature of 240° C. The resistors have a flame retardant coating and are specified for industrial and power electronics applications requiring stable performance in rugged,…
High Power Chip Resistors
CORPUS CHRISTI, TX (March 2007) – Providing power electronics engineers with more options in resistive devices that meet new power supply and voltage requirements, TT electronics IRC Advanced Film Division has extended the resistance range and voltage rating of their high power dissipation surface mount chip resistors. The SC-3 series resistors now feature resistance values…
Compact Surface Mount Resistor
The HSF Series resistor requires little surface area for mounting in telecom boards and is smaller than through-hole wire-wound components. It exceeds GR1089 lightning strike specifications. The resistor’s unspiraled design removes the chance of failure during lightning strikes, and it meets GR1089 specifications. When subjected to 1000V with the standard 10 x 1000 µs profile,…
