PTC DEVICE

摘要

There is provided a PTC device which allows compact connection as much as possible. Such PTC device comprises:
(1) a polymer PTC element 102 comprising:
(A) a polymer PTC component 102 comprising:
(a1) an electrically conductive filler, and
(a2) a polymer material; and
(B) a metal electrode 104 placed on at least one surface of the polymer PTC component;
(2) a lead 106 of which at least a part is positioned on the metal electrode of the PTC element; and
(3) a protective coating 108 which surrounds an exposed area of the PTC element, and
a hardened solder paste is present as a connection area 110 which electrically connecting the metal electrode and said at least a part of the lead.
