RNR/RNN Vishay Angstrohm Precision Hermetic Metal Film Resistors Established Reliability "S" Level, MIL-PRF-55182 Characteristics E and C FEATURES * Qualified to MIL-PRF-55182 Characteristics E and C (E and J for RNR75). * Performance exceeds the requirements of MIL-PRF-55182. * Excellent long term stability. * "S" Level reliability. * Hermetic glass enclosure is impervious to harmful environments. * Inert gas filled. * Low noise. For the highest degree of reliability, stability and uniformity of construction, Vishay Angstrohm hermetically-sealed metal film resistors are unquestionably the first choice. The true glass-to-metal hermetic enclosure seals the resistor element in an inert gas atmosphere and protects it from virtually all adverse environmental influences. The glass enclosure will withstand in excess of 3000 psi external pressure without leakage. The reliability and stability of Vishay Angstrohm hermetically-sealed resistors have been established by their use in nearly every military, missile, aerospace and oceangraphy program having the most demanding applications and the most hostile environments.
