High frequency porcelain cement resistance
The resistance wire is wound on a non-alkaline heat-resistant porcelain piece, and the outside is protected and fixed by heat-resistant, moisture-resistant, and corrosion-resistant materials. Cement-type resistors are made by putting the wire-wound resistors in a square porcelain frame and filling and sealing them with special non-combustible heat-resistant cement. Its symbol is the same as ordinary resistance. The specifications and characteristics of cement resistors are large and the resistance value is small.
Small size, shock resistance, humidity resistance and good heat dissipation, low price.
Fully insulated, suitable for printed circuit boards.
A wire is wound on the porcelain rod and then spot welded to make a precise resistance value.
High resistance value adopts metal oxide film body instead of winding method.
Excellent heat resistance, small temperature coefficient of resistance, linear change.
Resistant to short-time overload; low noise, resistance value.
Uses: current limiting, shunt, protection, etc.
