Resistance range:

Isotan

6 mΩ to 40 mΩ

Isaohm

20 mΩ to 100 mΩ

Manganin

5 mΩ to 35 mΩ

stamped designation of the resistance value is possible upon request.

Power range:

Isotan

1 W to 8 W,

Isaohm

0.5 W to 2.5 W,

Manganin

0.5 W to 1 W

Tolerance:

5 %; 3 %; (1 %)

Design:

Axial welded pins in tinned e-copper material or ISA 13. Pitch and other outer dimensions are variable due to compact design.

Application:

Switching power units Frequency converters Automotive applications Current supplies Precision measuring equipment.

Features:

High loads possible (short time exposure to 60 A); low inductance, inexpensive. Special designs lead to a very flexible product, that has been designed for close fit solutions while working under impulse loads.
