Compatibility & Fitment

• Suitable for a wide range of electronic applications requiring a power resistor.
• Commonly used in power supplies, audio crossovers, amplifiers, and load-testing circuits.
• Direct replacement for resistors with matching specifications (10W, 1 ohm, ±5%).

When to Replace

• Existing resistor is visibly burned, cracked, or shows signs of overheating.
• Circuit is malfunctioning due to resistor failure.
• Resistance measures as an open circuit (infinite resistance) or outside the ±5% tolerance range when tested with a multimeter.

Installation Tips

• Disconnect power to the circuit before removing the old component.
• Confirm the resistance value with a multimeter before installation.
• Mount the resistor with space for air circulation to allow for proper heat dissipation.
• Ensure leads are securely soldered to the circuit board or terminals.
