Composition resistors are considered one of the most reliable of all
electronic components. There are no windings or film, resulting in a
non-inductive resistor with excellent surge and high frequency char-
acteristics. The parts are also utilized in fusing applications. Hi-Rel
Group A or A&B Screening per Mil-R-39008 is available.

Peak pulse rupture voltage and joule ratings are dependent on resistance value, pulse wave form & repetition rate. Charts indicate the approximate rupture voltage based on capacitive
discharge non-inductive circuit, pulse width equates to one RC time constant. Refer to
Application Guide below and Engineering Guide
R-46. Verify selection by evaluating sufficient
protoypes under worst case conditions. Consult factory for assistance on all surge and fusing applications.

APPLICATION GUIDE
(refer to R-46 guide for additional info)
CC’s are often utilized in high frequency, fusing or pulse applications, including snub-
bers, lightning surges, grounding resistors, RFI suppression, etc. Depending on the ap-
plication, CC’s can often satisfy requirements of GR1089, ITU-K20, IEC61000-4-x, etc.
For fusing applications, use the peak pulse rupture voltage graphs and energy ratings as
a rough starting point to determine typical fusing levels. For surge applications, employ a
