Product specification

Cemented wirewound resistors AC01/03/04/05/07/10/15/20

FEATURES

• High power dissipation in

small volume

• High pulse load handling

capabilities.

APPLICATIONS

• Ballast switching

• Shunt in small electric motors

• Power supplies.

DESCRIPTION

The resistor element is a resistive wire

which is wound in a single layer on a

ceramic rod. Metal caps are pressed

over the ends of the rod.

The ends of the resistance wire and the

leads are connected to the caps by

welding. Tinned copper-clad iron

leads with poor heat conductivity are

employed permitting the use of

relatively short leads to obtain stable

mounting without overheating the

solder joint.

The resistor is coated with a green

silicon cement which is not resistant to

aggressive fluxes. The coating is

non-flammable, will not drip even at

high overloads and is resistant to most

commonly used cleaning solvents, in

accordance with “MIL-STD-202E,

method 215” and “IEC 60068-2-45”.
