An electrical component comprising:
- an electrical resistor comprising a PTC ceramic with a reference temperature exceeding 150° C.,
- wherein, at the reference temperature, a reference resistance is twice an amount of a minimum resistance of the PTC ceramic;
- a housing comprising a cover and enclosing the electrical resistor;
- and
- contact springs permanently incorporated in the housing and comprising at least an inner portion inside the housing in a cavity and an outer portion outside the housing,
- wherein the inner portions of the contact springs, which are located on the resistor are barb shaped,
- wherein a central, curved part of a barb shaped portion of each contact spring is arranged on the resistor,
- wherein an inner terminus of each spring is arranged on an inner wall of the cover of the housing,
- wherein the barb shaped portions of the contact springs on opposite sides of the resistor are clamped between the resistor and the cover, and
- wherein the cover provides a hard force to keep the housing closed and to fix the resistor.
