Power Resistors
TT electronics BI Technologies SMT Division has released a series of non-inductive power resistors with power ratings from 20 to 140 W, in transistor-style packages (TO-126, TO-220, TO263 and TO-247). Designated as the MHP and SMHP Series, the resistors are designed to provide complete thermal flow from the resistive element to the integral metal flange of the TO-style packages, giving design engineers the ability to specify them for high-wattage power electronics circuits that can experience elevated temperatures during operation. The devices are all rated for operation from 55° C to + 155° C. The MHP series resistors are available in five power ratings and four TO-style package types. For example, the MHP-20 series resistors are in three package styles TO126 (MHP20S), TO220 (MHP20) and the surface mount TO263 (D2Pak) (SMHP) packages, and are rated for 20 W power dissipation, with resistance ranges from 0.01Ω to 220Ω at maximum power, with tolerances of ± 5% and ± 1%. Thermal resistance is 5.9° C/W from the resistor’s "hot spot" to the package’s metal flange.
