1/2w100R Resistor (4-Band) (Metal oxide film) Code: 26719100

A 1/2-Watt (0.5W) 100-ohm metal oxide film resistor is an axial through-hole electronic component. It limits current or drops voltage in circuits, featuring excellent temperature stability, surge tolerance, and a flame-retardant coating. These resistors are commonly used in power supplies, analog circuits, and LED projects.

Key Technical Specifications

• Resistance Value:100 Ω (100 Ohms)
• Power Rating:5 W (1/2 Watt) at 70°C
• Tolerance:Typically ± 1% or ± 5%
• Max Working Voltage:300V to 350V (varies by manufacturer specification)
• Max Overload Voltage:600V to 700V
• Operating Temperature:-40°C to +155°C

Physical & Material Properties

• Construction:A ceramic core coated with a thin, non-flammable film of metal oxides (e.g., Tin Oxide).
• Leads:Axial, typically tinned copper, making them ideal for standard printed circuit boards (PCBs) or solderless breadboards.
• Dimensions:Standard 1/2W resistor bodies are roughly 8.5mm to 10mm in length and 3mm to 3.5mm in diameter.
