BI Technologies' new power resistor

TT electronics BI Technologies SMT Division has further extended its range of non inductive high density power resistors by providing power electronics design engineers with the means to specify the appropriate wattage to more accurately meet design specifications of their applications. The BHPR Series resistors are available in a TO-227 style, RoHS-compliant package and are now available in power ratings of 100-, 150-, 250-, 300- and 600W.

"In responding to our customers' design requests, we found that there were many opportunities for higher and lower wattage parts to help 'right-size' their power supply designs," explained Jim Rieley, sales director for the TT electronics BI Technologies SMT Division. "The addition of 100-, 150- and 600W power resistors will enable our customers to realize cost savings with the selection of the correct wattage for specific applications."

The high-density power resistors are suitable 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 1 to 1k, with tolerances to five percent 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 from -55C to 155C.

Typical low volume pricing for the BHPR Series resistors starts at 17.69 with lead times from stock to eight weeks. Samples are available immediately for engineering evaluation and customer prototypes.
