TECHNOLOGY
RMW:
The resistive element is a wire that is wound on a fiberglass core.
RMF:
The resistive element is a metal film resistor consisting of a metal layer deposited over a high-grade ceramic rod.
The terminals are crimped to the resistive body to provide a good mechanical and electrical contact. To ensure a flexible
assembling process, the resistors are offered in various terminals styles, such as long or short, one or two pins. The resistor body
and lead ends are housed within a rectangular ceramic case which is non-flammable, will not melt even at high overloads and is
resistant to most commonly used cleaning solvents, in accordance with IEC 60068-2-45.

MARKING
The resistor is marked with the resistor type designation. The
nominal resistance, the tolerance on the resistance, the
rated dissipation at T
amb
= 70 °C and the production date
(week and year), are printed in black on the resistor body.
For values up to 910
Ω
the R is used as a decimal point. For
values of 1000
Ω
or higher the letter K is used a decimal
point.
