Providing circuit designers with a way to integrate power resistors in minimal PC board space, TT electronics BI Technologies has developed a fully customizable power resistor network. Designed specifically for power line testers and attenuators, high voltage test equipment, motor drivers with current sense circuits, snubbers and high voltage power supplies, the power resistor networks are comprised of thick film resistors on a ceramic base and feature completely customizable resistor values, power, size and pinout.

“We are able to incorporate two to 10 resistors on each network, as well as modify technical specifications on a case-by-case basis, allowing us to meet each customer’s specific application needs,” said Brian Kane, BI Technologies’ director of product development for microcircuits and fixed films. “Plus, the networks feature a two-sided design option, resulting in higher density and increased space savings, particularly if the resistors have a low duty cycle for peak power dissipation.”

The custom power resistor networks are designated part 143-XXX, with each customer assigned a unique part number. The networks feature matching resistors in a SIP lead configuration, with a total available power rating of up to 10W and tolerance of 1%.
Lead time for custom power resistor networks are from 6 to 10 weeks.
