Construction
A ruthenium oxide based resistive film is fired onto a high
quality ceramic former. Brass caps are force fitted to the
HV32, 34 and 35 rods and plated steel caps to the 31 and 33
sizes. The resistor is adjusted to value by a helical cut in the
film, and the body is protected with a silicone coating.
Marking
Type reference, resistance value, tolerance and date code are
legend marked. The resistance values conform to IEC 62.
Solvent Resistance
The body protection and marking are resistant to all normal
industrial cleaning solvents suitable for printed circuits.
Terminations
Material
Solder coated copper wire.
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
