Construction
The resistance element is a precisely controlled thin film of
metal alloy on a high purity ceramic core, protected by a
cement coating applied so that terminations remain
completely clear. This permits a well defined body length
(clean lead to clean lead dimension L).
Marking
Resistors are colour coded with 4 or 5 bands depending on
value and tolerance. IEC 62 colours are used.
Solvent Resistance
The body protection and marking are resistant to all normal
industrial cleaning solvents suitable for printed circuits.
Terminations
Material
Strength
Solder-coated copper wire.
The terminations meet the requirements of
IEC 68.2.21
Flammability
The resistor coating will not burn or emit incandescent
particles under any condition of applied temperature or
power overload.
Solderability
The terminations meet the requirements of
IEC 115-1, Clause 4.17.3.2
