Military p/n's are given for reference only and do not imply qualification or exact interchangeability. 2Increased ratings avail. 3Max. voltage determined by E=(PR)1/2, E not to exceed value listed. 4 Option ER burn-in is performed at Mil-power rating and 25C ambient. Additional burn-in and Mil-screening options available. 5Standard reactance levels are quite high limiting use to DC or AC circuits <50KHz typ. (depending on size and resistance value). Specialty designs available for use at high frequencies, consult factory.
