1/4w680R Resistor (4-Band-R) (Metal oxide film) Code: 96802207

A 1/4W 680 ohm resistor is a standard electronic component used to limit current and drop voltage in circuits. It typically has a through-hole, axial-lead design perfect for breadboards and PCBs.

Core Specifications

• Resistance Value:680 Ω (Ohms)
• Power Rating:1/4 Watt (0.25W), which determines the maximum heat it can safely dissipate
• Tolerance:Usually ± 1% (Metal Film) or ± 5% (Carbon Film)
• Max Working Voltage:Typically 250V to 350V
• Operating Temperature:-55°C to +155°C

Resistor Color Codes

• 4-Band (5% tolerance):Blue, Gray, Brown, Gold
• 5-Band (1% tolerance):Blue, Gray, Black, Black, Brown

Common Applications

• Current limiting for standard LEDs (especially on a 9V or 12V power source)
• Transistor biasing and switching circuits
• Voltage dividers and basic RC filter circuits
