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.
