Precision Resistor Type PLC

The two terminal resistor type PLC was developed to serve

as an economic alternative to the type C-N for application

as current sensor in linearly regulated power units, switching

units, and current sources.

A decisive feature of the resistor is the high transient

overload capacity based on its good thermal abductance

from resistor material to aluminum substrate.

Remarks:

- Standard resistance values according to E6 ( Typ PLC E12 ) with the additionel values of 2 and 5

- Minimum quantity of other values on request

By an additional thermal contact of the aluminum carrier to

a dissipator, e.g., by depressing to a heat sink or casing,

the loading capacity can be raised to a manifold.
