HDN (Military RNR/RNN)
Vishay Angstrohm
Hermetic Metal Film Resistors, Military/Established Reliability,
MIL-PRF-55182 Qualified, Type RNR, Characteristics E and C
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.
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)
• Standard lead on the RNR product is solderable and on the
RNN is weldable
• MODEL RNC: For characteristics E and C (per
MIL-PRF-55182) terminal model RNR shall be used as a
substitute.
•For MIL-PRF-55182 Characteristics J, H and K product,
see Vishay Dale’s ERC (Military RNC/RNR) data sheet
Notes:
(1) Temperature characteristics E and C designate hermetically-sealed enclosure.
(2) Standard resistance values should be selected from the Resistance-Tolerance Decade table.
B tolerance available in all values.
(3) Contact factory for current QPL failure rates.
