RW318-102-KT

ECONOMY WIREWOUND RESISTORS 1 WATT to 10 WATT RESISTORS CAPACITORS COILS DELAY LINES RW SERIES RoHS Term.W is RoHS compliant & 260°C compatible Excellent performance at economy prices Inherent stability due to all-welded wirewound construction Wide resistance range: 0.01Ω to 25KΩ Standard tolerance is 5% (2% and 10% available) Available on exclusive SWIFTTM delivery program Available on horizontal Tape & Reel (1W-10W), or vertical Tape & Reel (1W-3W) RW Series resistors are manufactured on an exclusive automated system, resulting in significant cost savings. Ceramic core results in performance levels far superior to conventional fiberglass cores, especially in regards to overload capability, TCR, noise characteristics, and load life stability. Coating is flame resistant and offers excellent moisture and solvent resistance. OPTIONS Option X: Low Inductance Option P: Increased Pulse Capability Option FF: Flameproof Fusible (see application guide below) Option E: Low Thermal EMF Option F: Flameproof Coating Also available: cut & formed leads (horizontal and vertical), increased voltage, special marking, etc. Customized components are an RCD specialty!
