Fullerton, Calif. TT electronics BI Technologies has developed a new multi-turn 3-mm trimmer that combines a small size with an extended resistance range. The new RoHS-compliant 43 Series trimming potentiometers, with top adjust capabilities, are said to match the size of the industry's smallest multi-turn, sealed surface-mount trimmers.
Featuring an easy-to-adjust capability, the miniature 43 Series of cermet trimming potentiometers offers an extended resistance range of 10 Ω to 2 MΩ with standard tolerance to ±20% and absolute temperature coefficient of resistance (TCR) values to ±100 ppm/°C. The series provides power ratings to 0.125 W at 70°C. The operating temperature range is -65°C to 150°C.
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. Applications include cellular base stations, night vision systems, set-top boxes and portable test & measurement equipment.
Typical pricing for the multi-turn 3-mm potentiometers starts at approximately $1.60 in quantities of 10,000. Lead time is from stock to six to eight weeks.
