hot solder dipped leads, etc. Customized components
are an RCD specialty!
OPTIONS
Carbon composition resistors are considered as perhaps the most reliable
of all electronic components. There are no windings or film, resulting in
a truly non-inductive resistor with excellent pulse-withstanding capability.
Hi-Rel Group A Screening per Mil-R-39008 is available (specify option 37).
Note: composition construction isn’t as stable as other types especially in
humid conditions, and therefore isn’t suitable for precision applications.
Refer to RCD’s PR Series for improved environmental performance. Al-
cohol is recommended instead of aqueous rinsing. Use stress relief when
forming leads.

Peak pulse (rupture) voltage and joule ratings are dependent on resistance value, pulse wave form and repetition rate. Derate 25-50% for repetitive pulses and improved
stability/reliability. Repetitive pulse average power not to exceed wattage rating. Verify selection by evaluating under worst case conditions. Consult factory for assistance.
