Additional Details

The TMC3K series uses a carbon composition resistive element. This particular model has a resistance value of 15k Ohms with a tolerance of approximately ±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 adjustment types. The operating temperature range is generally between -10°C and +70°C. The 'TR' suffix usually indicates tape and reel packaging for automated assembly lines. The rotational life is commonly rated for hundreds of cycles depending on the specific model.
