Encapsulated in a silver aluminium housing, THS series power resistors are extremely stable, high quality wire wound resistors capable of dissipating high power in a limited space with relatively low surface temperature. Power is rapidly dissipated as heat through the aluminium housing to a specified heatsink. Target applications are vehicle braking and balancing resistors, capacitor charging and discharging, crowbar, filters and general electrical machinery.
Designed for heatsink mounting, latest THS series components are available with power ratings from 10 Watts up to 50 Watts and with ohmic values ranging from 0.01 Ω up to 50 kΩ. Thanks to their high quality materials and high stability, THS devices are able to withstand pulse energies of up to 320 Joules and overloads of up to 25 times rated power. Terminations are solderable tags but they can be modified to feature cable, threaded or fast-on connections. Standard inductances are kept to a maximum of 50ppm. Low inductance versions are available by using Ayrton Perry windings.
