Corrosion Resistant Ceramic Cement Resistor 5W 10W 0.25Ω-100Ω 5% Tolerance for High Power Applications
Corrosion resistant ceramic cement resistors designed for high-power applications with power ratings of 5W and 10W, available in resistance values from 0.25Ω to 100Ω with 5% tolerance.
Cement resistors feature resistance wire wound onto non-alkaline heat-resistant porcelain cores, sealed with special non-combustible heat-resistant cement within square porcelain frames. This construction provides excellent protection against environmental factors while maintaining stable electrical performance.
- Shock, moisture, and heat resistance with excellent heat dissipation
- Insulated design suitable for printed circuit board mounting
- Precision winding for accurate resistance values and extended service life
- Low resistance temperature coefficient with linear variation
- Short-term overload resistance and low noise operation
- Explosion-proof construction with protective casing
- Strong load capacity and corrosion resistance
