Cemented Wirewound Precision Resistors

FEATURES

• High power dissipation in small volume

• Ideal for pulse application

• TCR ± 100 ppm/K

• Maximum permissible hot spot temperature is

275 °C

• Lead (Pb)-free

• Tolerance 1 %

• Material categorization: for definitions of compliance

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-inflammable, will not drip even at high overloads and

is resistant to most commonly used cleaning solvents, in

accordance with IEC 60068-2-45.

Notes

• Resistance value to be selected for ± 1 % tolerance from E24 and E96
