SQB Series 20W to 40W TE SQ series wire wound resistors are high powered resistors which feature either wire or power oxide 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. These resistors are designed to provide a high insulation resistance, low-temperature coefficient and excellent TCR (Temperature Coefficient of Resistance), they are also fire proof construction. These high power resistors are suited to areas where efficient thermal performance is needed. Features - Inorganic Flame Proof Construction

- Stable TCR 300ppm/°C

- Choice of Style

- Wide Value Range

-Temp. Op. -55°C to +250°C
