TT/IRC Develops Low R Chip Resistor
Chip power resistors.
Corpus Christi, TX — TT electronics IRC has developed a highly stable low resistance chip resistor — a high power, low resistance device for current sensing applications. Designated the LRF3W-MIL Series, the chip resistors utilize high reliability thick film materials and are available with screening to MIL-PRF-55342 or customer drawing. The chip resistor package includes an uninterrupted 2-pad termination on the long sides of the resistor, maximizing thermal transfer and improving reliability.
According to the company, the LRF3W-MIL resistors combine high power, excellent stability, and extremely low resistance values in a compact 1225 package. This chip resistor is a suitable solution for high current sensing in demanding applications for the military and aerospace.
Resistance for the LRF3W-MIL Series chip resistors ranges from 0.003Ω to 1.0Ω, with a rated power of 3W at 70°C. Absolute TCRs are to ±100ppm/°C, ±250ppm/°C, and ±500ppm/°C, while available absolute tolerances are to ±1 percent, ±2 percent, ±5 percent and ±10 percent. Operating temperature ranges from -55 to +150°C.
