SQMW7R10J is a cement housed high power wire wound resistor from the Type SQ Series, designed for applications requiring efficient thermal performance and low cost. It features a 7W power rating with a resistance value of 0.10O (R10), wound on a fine non-alkali ceramic core and sealed in a ceramic case with inorganic silica filler. The resistor operates over a temperature range of -55°C to +155°C with a stable temperature coefficient of resistance (TCR) of ±300PPM/°C. Key electrical characteristics include 1000V AC voltage withstand for 1 minute and insulation resistance of 1000 MO at 500V. This flameproof construction resistor is suited for industrial applications where reliable thermal performance and flame resistance are critical design requirements.
