Non-inductive TO-227 Power Resistors Rated for up to 300W
TT electronics BI Technologies SMT Division has extended its range of non-inductive power resistors. Offered in a TO-227 package style, the BHPR Series resistors feature increased power ratings up to 250W and 300W.
"The four terminal BHPR 250 and 300 have one or two resistors in each package configured as a single element 300W or dual resistor 250W combination within the TO-227 style chassis-mount package," explained Jim Rieley, Sales Director for the TT electronics BI Technologies SMT Division. "These high power density components also provide excellent high frequency characteristics, as well as extremely low thermal resistance."
The resistors are ideal for a wide variety of applications including power supply snubbers, gate resistors, pulse generators, high frequency amplifiers, and dividers in high-end audio systems. The BHPR Series resistors have a resistance range of 1Ω to 1KΩ, with tolerances up to ±5% and TCRs to 100ppm/°C.
The resistors are designed to provide complete thermal flow from the resistive element to the integral base metal flange of the TO227-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 rated for operation within the range from -55 °C to +155 °C
The BHPR Series resistors feature low inductance M4 screw terminals, providing superior vibration durability. All BHPR Series devices are RoHS-compliant. Typical low volume pricing for the BHPR Series resistors starts at $17.69 with lead times from stock to 8 weeks. Samples are available immediately for engineering evaluation and customer prototypes.
