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.

POWER DERATING MARKING
NOTE: 1This typical data is taken from the average resistance shifts from numerous values. The actual shifts are dependent on the value.
2Any shift during moisture testing is due to the “load” (mini-load life) portion of the test and not due to the effect of moisture.

RESISTANCE
VALUE
The nominal resistance value expressed in
ohms is a four digit number. The first three
digits represent significant figures and the
last digit specifies the number of zeros to
follow.
When the value is less than 100 ohms, the
letter “R” is substituted for one of the
significant figures to represent the decimal
point. The resistance values shall follow
the Resistance-Tolerance Decade Table
(page 11).
Examples:
1.00 Ω = 1R00 10,000 Ω = 1002
10.0 Ω = 10R0 100,000 Ω = 1003
100 Ω = 1000 1,000,000 Ω = 1004
1000 Ω = 1001
