    Surface Mount Technology (SMT) Power Resistors Have Smaller Footprint

    Jan. 28, 2009
    Bourns, Inc. announced the company's expanded line of Surface Mount Technology (SMT) power resistors that offer excellent pulse protection, smaller footprint and simple series dropping functions enabling cost-effective automated assembly

    Bourns, Inc. announced the company's expanded line of Surface Mount Technology (SMT) power resistors that offer excellent pulse protection, smaller footprint and simple series dropping functions enabling cost-effective automated assembly. Designated Bourns PWR2010, PWR3014, PWR4318 and PWR5322, the new SMT power resistors feature high power density, low temperature coefficient with power ratings of ½ to 3 watts.

    The SMT resistors uniquely feature the characteristics of a wirewound resistor in a surface mount device (SMD) package providing improved pulse handling for greater stability over a wide temperature range and improved product longevity. Designed for a broad variety of applications that include instrumentation, telecommunications, base stations, automation and control applications, Bourns new SMT power resistors are an ideal solution for high-volume, automated assembly and as drop-in replacements for higher-priced and larger footprint parts.

    Bourns' SMT power resistors are designed with a special contour that maximizes the surface area of the device and minimizes the temperature rise of the package for improved stability over time. These SMT resistors have a temperature coefficient of resistance (TCR) of 20 PPM for resistance values greater than 10 ohms, 50 PPM for resistance values less than 10 ohms and 90 PPM for resistance values less than 0.99 ohms for increased stability and durability over a wide temperature range.

    Bourns' new SMT power resistors are available now. As a pricing reference, this new line is priced from $0.48-$0.77 in 5,000 piece quantities.
