Description:

Carbon film resistors are a fixed form type resistor. They are constructed out of a ceramic carrier with a thin pure carbon film around it, that functions as resistive material.

Applications:

Can be installed into the power circuits of:

• Power supplies and inverters

• Uninterruptible Power Supplies

• Energy saving lamps

• Electronic Ballasts

• Filament Protection of various types of lamps

• Some types of heaters

• For higher power circuits ask about the MF73

and MF74 series surge suppressors.

Specifications:
