1/2w4.7R Resistor (4-Band) (Metal oxide film) Code: 99518703

MINIMUM 50PCS ORDER NEEDED

A 1/2W 4.7-ohm Metal Oxide Film Resistor is a highly stable, flameproof electronic component used to limit current and drop voltage in circuits. Its 1/2 Watt power rating means it is designed to safely dissipate up to 0.5 W of heat.

Key Specifications

• Resistance Value:7 Ω (Ohms)
• Power Rating:5 W (1/2 Watt)
• Tolerance:Typically ± 5% (Standard for general-purpose resistors)
• Technology:Metal Oxide Film (Provides high thermal stability, low noise, and surge protection)
• Operating Temperature:-55°C to +155°C
• Mounting Type:Through-hole / Axial lead

Resistor Color Code

To identify the 4.7 Ω value, you can read the following color bands (from left to right):

1. Yellow(First Digit: 4)
2. Violet(Second Digit: 7)
3. Gold(Multiplier: × 0.1)
4. Gold(Tolerance: ± 5%)

Physical Characteristics

• Body Type:Cylindrical ceramic rod coated with a tin oxide-based film
• Dimensions:Roughly 8 mm to 9 mm in body length and about 2.5 mm in diameter
• Lead Wires:Axial wires on both ends for easy breadboard or PCB insertion
