TECHNOLOGY
RMWL:
The resistive element is a wire which is wound on a fiber glass core.
RMFL:
The resistive element is a metal film resistor consisting of a metal layer deposited over a high grade ceramic rod.
The mounting terminations are crimped to the resistive body to assure 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 in stainless
steel for lower solder spot. 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 its type designation. The
nominal resistance, the tolerance, the rated dissipation at
T
amb
= 70 °C and the production date (week and year), are
printed in red 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.
