Resistors For Direct Heat Sink Attachment

The KHA series of aluminium housed resistors from K S Instruments Pvt Ltd (Bangalore) is designed for direct heat sink attachment and is ideal for restricted space application. The KHA style is a range of high quality, high stability aluminium housed power wire wound resistors where the resistive element is wound onto high thermal conductivity ceramic formers, ensuring maximum contact for rapid heat transfer. This element is encapsulated in the aluminium housing by a transfer moulding process, which ensures a good humidity seal and a permanent compression fit. The encapsulate is a high temperature moulding compound and the special mould tool design ensures accurate concentricity of the resistive element inside the housing giving a high level of voltage protection. A wide range of resistance value is available in 5 to 300 W. Other features include: excellent heat transfers and smaller dimension; lower surface temperature; good electrical stability, reliability and mechanically very rigid; and dissipation of th
