The TMC2K2J-B470-TR is a trimmer potentiometer manufactured by Noble. It is a small, adjustable electronic component used to fine-tune or calibrate circuits. This specific model has a resistance value of 470 ohms and a B taper, which refers to the logarithmic relationship between the trimmer's adjustment and the resulting resistance change. The 'TR' suffix indicates that it is supplied in tape and reel packaging, suitable for automated assembly processes.

Additional Details

The TMC2K2J series are carbon composition trimmer potentiometers. The power rating is typically 0.1W at 50°C, derated to 0W at 85°C. The operating temperature range is commonly -10°C to +85°C. The rotational life is specified in terms of the number of cycles the trimmer can withstand while maintaining its electrical characteristics. The exact dimensions can be found in the manufacturer's datasheet. The 'J' in the part number usually denotes the tolerance (e.g., ±5% or ±10%).
