RN73R Metal Film Flat Chip Resistors

KOA Speer RN73R Metal Film Flat Chip Resistors are designed to meet the demands of high-heat and high-moisture applications. These KOA Speer resistors provide improved electrolytic corrosion resistance and high stability compared to existing RN73 thin film resistors. RN73R offers high heat tolerance with a -55°C to +155°C operating temperature range. The resistors feature a rated ambient temperature of +85°C and improved moisture tolerance of 85% for 1000 hours at 85°C.
