220 Ohms Black VR Original (200 Ohms/B221) Code: 47206520

A 220-ohm variable resistor (often called a potentiometer or “trimpot”) is a three-terminal component used to continuously adjust and limit current in an electrical circuit. It is commonly used for tuning voltage, calibrating circuits, and dimming in small DIY electronics projects.

Common specifications for a 220 Ω variable resistor:

• Resistance Value:220 Ohms (Ω)
• Resistance Tolerance:Typically ±10% or ±20%
• Power Rating:Standard models range from 0.1W to 0.5W
• Maximum Voltage:Usually rated up to 50V to 100V
• Type/Construction:Available as thumb-adjust knobs, panel-mount potentiometers, or tiny PCB-mount trimpots (labeled with the code “221”)
• Operating Temperature:-25°C to +85°C
