Power resistors offer improved performance at a lower cost
Tyco Electronics is announcing a new addition to its CGS range of power resistors, namely the aluminium-housed THS series power resistors that are based on the high-performance HS series devices. The new models feature the same basic performance levels but at a lower cost.
Encapsulated in a silver aluminium housing, the 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 include vehicle braking and balancing resistors, capacitor charging and discharging, crowbar, filters and general electrical machinery.
Designed for heatsink mounting, the latest THS series components are available with power ratings from 10-50W and with ohmic values ranging from 0.01ohm up to 50kohm. Thanks to their high-quality materials and high stability, the THS resistors are able to withstand pulse energies of up to 320J and overloads of up to 25 times rated power.
Terminations are solderable tags but they can be modified to have 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.
THS series power resistors are readily available through Tyco Electronics' distributor Farnell. Testing to conform to relevant international, MIL or customer specifications is available through Tyco Electronics.
