1/2w22R Resistor (4-Band) (Metal oxide film) Code: 36385024

A 1/2 W 22 Ω metal oxide film resistor is a fixed axial-leaded component designed for high-temperature stability, flame resistance, and low-noise. It typically features a ceramic core coated with a superheated metal oxide layer (like tin oxide and antimony oxide).

Core Specifications

• Resistance:22 Ohms (Ω)
• Power Rating:1/2 Watt (0.5 W)
• Tolerance:Typically ±5% (indicated by a gold band), occasionally ±2% or ±1%
• Maximum Working Voltage:250 V to 350 V
• Operating Temperature:-55°C to +155°C
• Mounting Style:Through-hole, axial leads
• Typical Dimensions:~9 mm length × ~ 3.2 mm diameter

Resistor Color Code

• 4-Band (5% Tolerance):Red (2), Red (2), Black multiplier (× 1), Gold (± 5%)
• 5-Band (1% or 2% Tolerance):Red (2), Red (2), Black (0), Red multiplier (× 100), Brown or Red for tolerance

Key Benefits & Applications

• Flameproof Construction:Ideal for circuits that require protection against overheating and burning.
• Surge Handling:It offers superior overload and surge handling capabilities compared to carbon film equivalents.
• Applications:Commonly used in power supplies, current limiting, snubbers, and general-purpose analog or audio circuits.
