Series SA (standard), MA (mini), PC (radial), and Q (economy) are
designed for precision circuits (DC
5
and low frequency AC). The standard
construction features well-proven wirewound technology. Customized WW
and NiCr film designs are available for high-frequency operation. All
models are preconditioned thereby enabling excellent stability/reliability.

Option ER burn-in is performed at Mil-power rating and 25°C ambient. Additional burn-in and Mil-screening options available.
5
Standard reactance levels are quite high limiting
use to DC or AC circuits <50KHz typ. (depending on size and resistance value). Specialty designs available for use at high frequencies, consult factory.

POWER DERATING:
Series SA/MA/PC40 resistors shall be derated
according to Curve A; Series Q & PC45 per Curve B (resistors with 0.1% or
tighter tolerance to be derated 50% per Mil-Std-199).
