Bourns RJ12 Trimpot Trimming Potentiometers
Bourns RJ12 Trimpot Trimming Potentiometers are sealed, multiturn cermet potentiometers designed for precise resistance adjustment in calibration and circuit-setting. These potentiometers provide a standard resistance range from 10Ω to 1MΩ with a 1W power rating at 70°C and operate over a temperature range from -55°C to +150°C. The RJ12 potentiometers meet MIL-PRF-22097 requirements and are available with panel-mount and printed circuit pin options for flexible integration. These trimming potentiometers find applications in instrumentation adjustment and signal trimming.
