25ohm Panel / Chassis Mount Resistors:

21 Products Found
We offer ranges of Panel / Chassis Mount Resistors with values from 500µΩ to 0.5GΩ. Below are examples of our manufacturers and their technologies.

A panel/chassis mount resistor is manufactured using wirewound resistor technology and features a ceramic core that is moulded into an extruded aluminium chassis mount housing. The wirewound design maximises pulse handling and the aluminium housing allows for superior heat conduction. TE Connectivity offers chassis mount resistors that are engineered for a variety of applications, including motor control, braking systems, welding, and X-rays.

Vishay offers wirewound, industrial power, aluminium housed chassis mount resistors such as the RHXXX Series. These offer moulded construction for total environmental protection, with complete welded construction. They meet applicable requirements of MIL-PRF-18546. They are available in non-inductive styles (type NH) with Ayrton-Perry winding for lowest reactive components

They mount on chassis to utilize heat-sink effect, and offer excellent stability in operation (< 1 % change in resistance).

The WH series of panel/chassis mount resistors from TT Electronics/Welwyn are 50W axial leaded wirewound resistors with solder-dipped copper clad steel terminations. Cap and lead assemblies are fitted to a high purity ceramic substrate. The resistive element is wound onto the substrate and welded to the caps. The wound rod is then moulded and fitted into aluminium housing to give optimum stability and reliability. The aluminium housed wirewound resistor is suitable for severe environments and excellent thermal conductivity to heatsink. Typically used in high power applications.
