Definitions

PTC resistors can therefore be used as overload protection for circuits. Because of their limited conductivity - carbon-filled polymers, for example, have a specific resistance greater than 1 ⁇ cm - their practical application generally limits them to nominal currents up to approx. 8 A at 30 V and up to approx. 0.2 A at 250 V.
the filler provided in the first resistance material contains electrically conductive particles in the form of carbon and / or a metal, such as nickel, and / or at least one boride, silicide, oxide and / or carbide, such as TiC2, TiB2, MoSi2 or V2O3, each in undoped or doped form.
the concentration and the geometric dimensions of the filler provided in the partial resistance bodies 5 are dimensioned such that current commutation can take place locally from a partial resistance body 4 to a partial resistance body 5.
the filler provided in the partial resistance bodies 5 can, but need not necessarily, form continuous current paths.
the proportion of the filler forming the partial resistance body 4 can be between 15 and 50 vol% and that of the filler forming the partial resistance body 5 between 5 and 40 vol%, the polymer matrix embedding the filler should have a proportion of 20-60 vol% of the resistance body 3 .
the resistance bodies 3 can subsequently be cut up by cutting.
the resistance bodies produced in this way can have, for example, a length of 0.5 to 20 cm and end faces of, for example, 0.5 to 10 cm2.
the end faces of the resistance structure 3 having a sandwich structure are smoothed, for example by lapping and polishing, and can be connected to the contact connections 1, 2, for example, by soldering with a low-melting solder or by gluing with a conductive adhesive or by hot pressing.
the current-limiting elements according to FIGS. 6 to 8 can be produced as follows:
the disks 50 and ring bodies 51 can be produced from powdered ceramic material, such as from suitable metal oxides, by pressing and sintering.
the diameters of the disks can be, for example, between 0.5 and 5 cm and those of the ring bodies between 1 and 10 cm with a thickness of, for example, between 0.05 and 1 cm.
the disks 50 are stacked with the contact disks 6 lying between them.
the contact washers 6 may have holes 7 of any shape in the edge area and may even be designed as a grid.
the stack is placed in a mold.
the free space between the contact disks 6 is then filled with polymeric PTC material to form the ring body 40 and the cast stack is cured.
the top and bottom of the stack are then contacted.
