Betatronix offers various types of elements to meet any customer requirement
Cermet combines ceramic with precious metals to created a resistive material.
Stable resistance over time and temperature change
Good Frequency response
Temperature coefficient better than conductive plastic but worse than wirewound
Higher surface roughness than conductive plastic
Modern carbon film element made with plastic resin and carbon powder.
Most economical option
Better noise performance that cermet
High surface smoothness, longer life than cermet
Worse moisture resistance, temperature coefficient, power dissipation, and wiper current capacity than cermet
Stable over time and temperature change
Low static noise
Narrow range of resistance
