Resistor 0.1 ohm 1W

The 0.1 Ohm 1W Resistor is a low-value through-hole resistor rated at 1W. Its very small resistance turns the current flowing through it into a small, measurable voltage, so it is widely used as a current-sense or shunt resistor in power supplies, battery chargers, LED drivers and motor controllers. The axial leads fit breadboards, stripboards and printed circuit boards.

0.1 Ohm 1W Resistor – Key Features

• Resistance value: 0.1 Ohm (R10)
• Power rating: 1W
• Through-hole part with axial leads
• Suitable for current sensing and shunt use
• Fits stripboards and PCBs

Applications

Makers, students and technicians use it in many kinds of projects, for example:

• Current sensing in power supplies and chargers
• Shunt resistor for ammeters and current meters
• Over-current protection in motor and LED drivers
• Emitter resistors in audio amplifier output stages
• Repair work, student labs and prototyping

Usage Tips

At 0.1 Ohm the part reads close to zero on many multimeters, so check it with a low-ohm range or a four-wire measurement. Keep the power below 1W (about 3.1A continuous) and allow some space around it for cooling.
