Construction
The tin oxide resistance element is deposited onto a high
purity ceramic rod. End caps are force fitted and termination
wires are welded to the end caps. The element is adjusted to
the required resistance value by a helical cut; finally a cement
protection is applied to the resistor body prior to marking
with indelible ink.
Terminations
Material
Resistor sizes up to and including the MO3S
use solder coated copper terminations. MO4S
and MO5S use solder coated steel cored
terminations.
Strength
The terminations meet the requirements of
IEC 68.2.21.
Solderability The terminations meet the requirements of
IEC 115-1, Clause 4.17.3.2.
Marking
MO1/2S, MO1S, MO2S and MO3S resistors are colour coded
with four bands. IEC 62 colours are used. For larger sizes type
reference, resistance value and tolerance are legend marked.
The resistance value marking conforms to lEC 62.
Solvent Resistance
The body protection and marking are resistant to all normal
industrial cleaning solvents suitable for printed circuits.
Flammability
The resistor coating will not burn or emit incandescent
particles under any condition of applied temperature or
power overload.
