Coefficient: *Short Time Overload: Rated Load: Voltage Withstand: Insulation Resistance: Temperature Cycle: Load Life: Moisture-proof Load Life: Incombustability: Max. Overload Voltage: *Metal 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 Type SQP - Horizontal 35 3 2W: 23 3 inorganic silica filler. This design provides a resistor with high d insulation resistance, low surface H temperature, excellent T.C.R., and L entirely fire proof construction. These resistors are ideally suited to a range of areas where low cost, and efficient thermal performance are important design criteria. Metal film cores adjusted by laser spiral are used where the resistor value is above that suited to wire. Similar performance is obtained although short time overload is slightly derated.
