The TE Connectivity power wire wound resistors either have wire or power oxide film elements. The SQ series resistors are wound or deposited on a fine non-alkali ceramic core then embodied in a ceramic case and sealed with an inorganic silica filler. This design provides a resistor with high insulation resistance, low surface temperature, excellent Temperature co-efficient of resistance (TCR), and entirely flameproof construction.
