Construction of SQP type cement resistors:
Product Description:
cement resistors are made by cut trimming metal oxide film core or winding resistance wires around non-alkaline ceramic core, either is added with a layer of heat and humidity resistant and non-corrosive protective material. The wire wound resistor or metal oxide resistor is then placed in a square ceramic package sealed with special nonflammable heat-resistant cement
Material Specifications (SQ)
Core :High purity grade alumina ceramic rod.
Terminals :Tin/lead plated (Lead (Pb)-free will be 100 % tin).
Body : Steatite ceramic case with inorganic potting compound.
Element :Copper-nickel alloy, nickel-chrome alloy, resistive wirewound or power film depending on resistance value.
Features
1, shock, moisture, heat and good heat, low prices and other characteristics.
2, completely insulated, suitable for printed circuit boards.
3, porcelain rod winding and then welded joints, the system made a precise resistance and extend the life.
4, high resistance value using metal oxide film (MO) instead of winding way.
5, excellent heat resistance, resistance temperature coefficient is small, a linear change.
6, resistance to short time overload, low noise, resistance has not changed year after year.
7. Explosion-proof performance, and play a protective role
Applications :
Power supplies/Voltage dividers/Motor controllers/Automotive applications/Power electronics circuits
