Product Description
High Power Wirewound Cement Resistor Overview
Cement resistors are high-power wirewound resistors sealed with fire-resistant clay. The resistance wire is wound onto non-alkaline heat-resistant porcelain pieces, wrapped with protective materials, and placed into square porcelain frames sealed with special non-combustible heat-resistant cement.
Key Technical Features
- Power ratings: 5W, 10W, 20W, 100W options available
- Resistance range: 0.1Ω to 10kΩ with ±5% tolerance
- Excellent shock resistance and vibration durability
- Superior moisture and heat resistance properties
- Effective heat dissipation for high-power applications
- Insulated construction suitable for printed circuit boards
- Low resistance temperature coefficient with linear variation
- Short-term overload resistance and low noise operation
- Explosion-proof design with protective casing
