1/2w2.2k Resistor (4-Band) (Metal oxide film) Code: 83686200

A 1/2W 2.2kΩ resistor (or 2k2) is a fixed passive component that provides 2,200 ohms of resistance and safely dissipates up to 0.5 watts of power. It is commonly used in general-purpose electronic circuits for current limiting, voltage division, and biasing.

Core Specifications

• Resistance:2 kΩ (2,200 ohms)
• Power Rating:5 Watt (1/2W), indicating its capacity to safely convert power into heat
• Tolerance:Typically available in ± 1% or ± 5%
• Operating Temperature:Usually -55°C to +155°C
• Construction:Available as standard through-hole (axial) parts in either carbon film or metal film (metal film provides higher precision and thermal stability).

Color Codes

You can identify the resistance value by looking at the colored bands on the resistor body:

• 4-Band Resistor:Red (2), Red (2), Red (Multiplier: × 100), Gold (Tolerance: ± 5%)
• 5-Band Resistor:Red (2), Red (2), Black (0), Brown (Multiplier: × 10), Brown (Tolerance: ± 1%)

Sourcing & Replacement

• Where to buy:Easily obtainable from local electronic markets in Old Dhaka (e.g., Patuatuli ,Nawabpur) or online platforms like ChanBD.com Bangladesh.
• Compatibility:If you need to replace it and a 1/2W is unavailable, you can use a higher wattage resistor (like a 1W or 2W). You can also use a 1/4W (0.25W) resistor, but only if the circuit’s current/voltage will not cause the component to exceed 0.25W of power.
