Additional Details

The TMC3K series incorporates a carbon composition resistive element. This particular model has a resistance value of 100k Ohms with a tolerance that can typically be ±30%. The power rating is commonly in the range of 0.1 to 0.25 Watts. Designed for through-hole mounting on PCBs, these trimmers are generally single-turn adjustments. The typical operating temperature range for these parts is between -10°C and +70°C. The 'TR' suffix usually means tape and reel packaging for automated assembly lines. The rotational life is commonly rated for hundreds of cycles depending on the specific requirements.
