The TMC2KJ-B100K is a trimmer potentiometer manufactured by Noble. It is a small, adjustable resistor used for fine-tuning circuits. This particular model has a resistance of 100 kilohms (100,000 ohms) and a B taper, meaning the resistance changes logarithmically as the adjustment screw is turned. This type of taper is often used for audio volume controls because it more closely matches the way human hearing perceives sound intensity.

Applications

• Audio equipment calibration.
• Setting bias currents in amplifiers.
• Adjusting sensor sensitivity.
• Calibrating electronic test instruments.
• Fine-tuning filter circuits.

Features

• 100 kOhm Resistance
• B (Logarithmic) Taper

• Carbon composition element
• Screwdriver slot for easy adjustment
• Durable construction

Benefits

• Precise Adjustment: Allows for accurate and stable resistance settings, critical for calibration and fine-tuning.
• Versatile Application: Suitable for a wide range of circuits and applications.
• Cost-Effective: Provides an economical solution for adjustable resistance requirements.
• Reliable Performance: Offers consistent performance over time.
• Ease of Use: Simple adjustment via a screwdriver slot.

Additional Details

The TMC2KJ series trimmers typically have a power rating of around 0.1W and an operating temperature range of -10°C to +70°C. The rotational life is a key specification, indicating the number of cycles the trimmer can withstand while maintaining its electrical characteristics. The precise dimensions, resistance tolerance, and other details are available in the manufacturer's datasheet. The trimmer is designed for through-hole mounting on printed circuit boards.
