Abstract (en)

An electrical component consists of a positive temperature coefficient (PTC) polymer element (1) with neck sections (2) at right angles to the main current direction (3). The opening angle of the neck section in the main current direction longitudinal plane is at least 100 degrees.

Abstract (de)

Beschrieben wird ein PTC-Polymerelement (1) als Teil eines elektrischen Bauteils mit einer neuen Struktur, bei denen Öffnungswinkel (a) auf beiden Seiten von Einschnürungen (2) in dem PTC-Polymermaterial zumindest 100° betragen. Dadurch läßt sich ein verbessertes Ansprechverhalten erzielen, und in Verbindung mit weiteren Merkmalen wird der Aufbau schneller, stromtragfähiger und spannungsfester PTC-Polymerelemente möglich. <IMAGE>
