OPEN-AIR LOW VALUE CURRENT SHUNT RESISTORS 0.001Ω to 0.15Ω, 1 WATT to 5 WATT OA SERIES RoHS RESISTORSCAPACITORSCOILSDELAY LINES New narrow profile design offers significant space savings! Term.W is RoHS compliant & 260°C compatible Industry’s widest range and lowest cost! Tolerances to ±0.5%, TC’s to ±20ppm Available on exclusive SWIFT TM delivery program! Option S: Axial lead (unformed element) Option E: Low Thermal EMF Option A: Stand-offs formed into lead wires Optional pin diameters and pin spacing RCD’s OA series offers cost-effective performance for a wide range of current shunt/sense applications. The non-insulated open-air design features non-inductive performance and excellent stability/overload capacity. Numerous design modifications and cutom styles are available... current ratings up to 100A, surface mount designs, military screening/ burn-in, marking, insulation, intermediate values, etc. Custom shunts have been an RCD specialty over 30 years!
