FEATURES
•Qualified to MIL-PRF-55182 Characteristics E and C
(E only for RNR75)
•Performance exceeds the requirements of
MIL-PRF-55182
•“S” Level reliability
•Hermetic glass enclosure is impervious to harmful
environments
•Inert gas filled
•Low noise (- 40 dB)
•For MIL-PRF-55182 Characteristics J, H and K product,
see Vishay Dale’s ERC (Military RNC/RNR) data sheet
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.
