Keywords:resistor power? SMT resistors Bourns? protection pulse?

Bourns Inc. has expanded its line of SMT power resistors with parts that offer high pulse protection, a smaller footprint and simple series dropping functions, enabling cost-effective automated assembly, according to the company.

Designated PWR2010, PWR3014, PWR4318 and PWR5322, the SMT power resistors feature high power density, low temperature coefficient with power ratings of 0.50W to 3W.

The SMT resistors feature the characteristics of a wirewound resistor in a SMD package, providing improved pulse handling for greater stability over a wide temperature range and improved product longevity. The SMT resistors have a TCR of 20ppm for resistance values greater than 10次, 50ppm for resistance values less than 10次and 90ppm for resistance values less than 0.99次 for increased stability and durability over a wide temperature range.

Applications include instrumentation, telecommunications, base stations, automation and control. Bourns' SMT power resistors can also be used for high-volume, automated assembly and as drop-in replacements for higher-priced and larger footprint parts.

The resistors are now available, and price range is $0.48-$0.77 in 5,000-piece quantities.
