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.
