Providing design engineers with a space-saving trimmer featuring an extended resistance range, TT electronics BI Technologies developed a RoHS-compliant, 3-mm multi-turn potentiometer with top adjust capabilities. Designated the Model 43 trimmer, the cermet trimming potentiometer's size matches the smallest multi-turn sealed surface mount trimmers in the industry, according to the company. The 43 Series devices are suited for applications involving cellular base stations, night vision systems, set-top boxes, and portable test and measurement equipment.
The cermet trimming potentiometers have a resistance range of 10 ê to 2 Mê, with standard tolerance to +/-20% and absolute TCR values to +/-100 ppm/°C; with power ratings to 0.125 W at 70°C. Operating temperature range is -65°C to +150°C, and the devices are RoHS compliant. Available in J-hook surface mount packaging, the 43 Series potentiometers are compatible with automated placement equipment, and are sold in tape and reel packaging. Typical pricing for the 3-mm multi-turn potentiometers starts at around $1.60 in quantities of 10,000 pieces. For more information, visit www.bitechnologies.com/products.
