RMS

DESCRIPTION

Dielectric withstanding voltage of

the insulation for 1 minute

700 V

A metal glazed film is deposited on a

high grade ceramic body. After a

helical groove has been cut in the

resistive layer, tinned electrolytic

copper wires are welded to the

end-caps. The resistors are coated

with a light blue lacquer which

provides electrical, mechanical, and

climatic protection.

The encapsulation is resistant to all

cleaning solvents in accordance with

“MIL-STD 202E, method 215” and

“IEC 60068-2-45”.

Basic speciﬁcations

Climatic category (IEC 60068)

Stability after:

IEC 60115-1B

55/155/56

load (1000 hours)

∆R/R max.: ±1.5% + 0.1 Ω

accelerated damp heat test (6 days) ∆R/R max.: ±1.5% + 0.1 Ω

long term damp heat test (56 days)

Noise

∆R/R max.: ±1.5% + 0.1 Ω

max. 5 µV/V
