BI Technologies SMT Division announces a non-molded power resistor rated up to 75 W. Designated the BHP75 Series, the resistor is housed in a TO-220 opened screened substrate package and features an insulated tapered venturi bonded to the substrate for maximum heat dissipation. Typical applications for the BHP75 resistor include higher wattage switch-mode power supply circuits, motor control and drive circuits, inverters and industrial power equipment. The BHP75 Series resistors are rated for 75 W power dissipation at tab temperature maintained at 25°C or less than 75 W. Resistance ranges from 1Ω to 100KΩ, with tolerances of ۫% and ۯ%. TCRs range less than 100ppm/°C, with maximum DC operating voltage of 250 V and dielectric-withstanding voltage of 1 KV. Thermal resistance is 1.3°C/W from the resistor’s hot spot to the package’s metal flange and operating temperature range is 㫏°C to 𫐃°C.
