These ultra precision resistors are designed and
produced for critical parameter applications. They are
available for established reliability military and/or
commercial applications requiring state of the art
precision and stability.
Construction features may vary slightly between
commercial and military styles, but both are produced
under the same rigid quality control system required
by the tightest military specifications. Both are
produced in the same production line using the same
highly trained operators required to produce the
established reliability product.
Whether military or commercial, all resistors are
carefully monitored during assembly, winding, coating,
and stabilization procedures to assure high quality
standards even when their prescribed parameters are
non critical. Premium grade selected wire is control
stress wound on special designed bobbins. All
MIL-R-39005 SPECIFICATIONS:
Temperature Range
terminations are welded to reduce contact noise and
thermal EMF. Extensive accelerated aging programs
both before and after calibration assure precise initial
accuracy and high resistance stability.
Encapsulation is accomplished by transfer molding
with special moisture resistant epoxy or by unique
dry air chamber epoxy shell technique for established
reliability parts. A resilient inner coating is used to
minimize internal stresses on all parts.
The established reliability military parts are burned in
100 hours at 125°C ambient as part of group A
acceptance testing. Documentation and special test
are available upon customer request to meet your
unique requirements.
