Expanding a metal foil/metal element construction into higher power resistors, Ohmite has combined the internal technology of FCSL series with the TO-220 packaging of their TBH series to achieve handling in excess of 25A.

The low TCR characteristics of the FCSL construction, using pure Ni-Cu alloys, result in a more stable resistor than alternative thick film devices, said the supplier.

With an operating temperature range of -55 to +150ºC and a temperature coefficient of 0.03(-10)Ω at +/-100ppm, 11-10kΩ at  +/-50ppm, the TBH has a resistance range of 0.03-10kΩ and a maximum operating voltage of 350V.

Applications for the new resistors include power supplies, industrial controls, automotive steering, pre-load/damping, snubber/bleeder and current sensing.
