What is a 0.1 Ohm 10W Cement Resistor?
A cement resistor is a fixed wire wound resistor encased in a heat-resistant cement housing. It is designed to handle high power and efficiently dissipate heat, making it ideal for high-power applications.
The 0.1 Ohm power resistor has the following key specifications:
- Resistance: 0.1 Ohm
- Power Rating: 10W
- Tolerance: 5%
- Construction: Wire wound
- Housing Material: Cement-coated
This resistor is often used in power circuits, motor control applications, and current sensing because of its low resistance and high power handling capability.
Specifications of a 0.1 Ohm 10W Cement Resistor
Understanding the technical specifications of a 10W 0.1 Ohm resistor is important to ensure it fits your application. Below are the key specifications:
- Resistance Value – 0.1 Ohm, which limits current to a minimal level.
- Power Rating – 10 Watts, which means it can handle significant power dissipation without overheating.
