5 KΩ Linear Rotary Potentiometer – B5K, 3‑Pin Variable Resistor
A classic, high‑precision rotary potentiometer that provides a smooth, linear resistance adjustment from 0 Ω to 5 kΩ. Housed in a compact, rugged B5K package, the device features three gold‑plated pins (two outer fixed terminals and a central wiper) that let you dial in exact resistance values for voltage dividers, biasing networks, or sensor calibration. Ideal for laboratory benches, prototype boards, and teaching labs, this component lets students explore fundamental concepts such as Ohm’s law, voltage division, and the impact of variable resistance on circuit behavior in real time.
What Students Will Learn & Why It’s Great
- Hands‑on circuit analysis: Build and tweak voltage dividers, audio attenuators, and speed‑control circuits while observing the immediate effect of resistance changes on voltage and current.
- Design iteration: Experiment with linear taper versus logarithmic taper and understand the importance of taper selection in audio and sensor applications.
- Practical troubleshooting: Use the potentiometer to simulate sensor drift, calibrate signal paths, and practice measuring resistance with multimeters and oscilloscopes.
Key Features
- Linear taper (10 % tolerance) for predictable, proportional adjustment
- Durable carbon film resistive element with a 0.5 W power rating
- 6 mm shaft with knurled knob for precise manual control
- Through‑hole mounting (0.6 mm lead pitch) for easy insertion on breadboards and prototype PCBs
- Low noise and stable performance over a wide temperature range (‑40 °C to +85 °C)
Because it combines reliable performance, easy handling, and a clear educational impact, the B5K 5 kΩ linear rotary potentiometer is a go‑to component for any electronics curriculum or hobbyist project that demands accurate, adjustable resistance.
