TECHNOLOGY
A homogenous film of metal alloy is deposited on a high grade ceramic body. After a helical groove has been
cut in the resistive layer, tinned connecting wires of electrolytic copper or copper-clad iron are welded to the
end-caps. The resistors are coated with a red, non-flammable lacquer, which provides electrical, mechanical
and climatic protection. The encapsulation is resistant to all cleaning solvents in accordance with “MIL-STD-
202E, method 215” and “IEC 60068-2-45”.

MOUNTING
The resistors are suitable for processing on automatic insertion equipment, cutting and bending machines. A
radial taped version economizes space on the PCB. The double kink style offers great advantages for
manual insertion improving the mounting stability for the customer. They have a real
snap in
function to fix
the resistor in PCB without weakening the connecting leads.
