1/2w470R Resistor (4-Band) (Metal oxide film) Code: 81491242

A 1/2W 470-ohm metal oxide film resistor is an axial-lead electronic component designed for general-purpose and high-reliability circuits. It provides excellent stability, flame-retardant protection, and low current noise, making it highly suitable for everyday prototyping and electronics repair.

Core Specifications

• Resistance Value:470 ohms
• Power Rating:5 Watts (1/2W)
• Tolerance:Typically ± 1% to ± 5%
• Operating Temperature:-55°C to 155°C (derated at higher temperatures)
• Max Working Voltage:Typically 350V
• Color Code (5-band):Yellow, Violet, Black, Black, Brown (for ± 1% tolerance)

Key Properties

• Construction:Formed by depositing a thick metal oxide film (usually tin and antimony oxide) onto a high-purity ceramic core.
• Flame Retardant:Features an excellent flame-retardant silicone coating for safe operation under high-temperature loads.
• Advantages over Carbon/Standard Metal Film:Metal oxide resistors can operate at significantly higher temperatures and withstand higher power surges than standard metal film or carbon film resistors.
