5857-BR001 is a PTFE-insulated hookup wire designed for high-temperature and high-reliability applications. It features an 18 AWG (19/30) silver-plated copper conductor with a nominal diameter of 0.050 inches and PTFE insulation with a 0.010-inch wall thickness, resulting in an overall insulation diameter of 0.069 ± 0.005 inches. The wire is rated for 600 VRMS and operates over a wide temperature range of -60°C to 200°C, with a maximum pull tension of 14.9 lbs and a recommended bend radius of 10X cable diameter. It meets UL AWM/Style 1213 (VW-1), MIL-W-16878/4 (Type E), and NEMA HP3-EXBHE specifications, and is fully RoHS compliant. This wire is ideal for aerospace, military, and industrial applications requiring excellent thermal stability and electrical performance.
