Over-current protection apparatus |
摘要 |
The present invention discloses an over-current protection apparatus, which comprises a current-sensitive element and at least two electrodes. The current-sensitive element is composed of a positive temperature coefficient (PTC) conductive composition, which includes at least one polymer, a conductive filler and a non-conductive filler. The melting point of the polymer is greater then 110° C., and the vicat softening point of the polymer is smaller than 110° C. for improving the conductivity and thermal stabilization of the over-current protection apparatus.
