Title:
SURFACE MOUNTING VARISTOR
Document Type and Number:
WIPO Patent Application WO/2011/162181
Kind Code:
A1
Abstract:
Disclosed is a surface mounting varistor for high-voltage and large-current pulses, which does not have a risk of burning a substrate.
The exterior material of the varistor (1) has a double (double layer) structure composed of a first mold layer (13) and a second mold layer (15), and leg sections having a predetermined height are formed on the bottom portion of the exterior material. As a result, due to a space (gap) formed between a varistor element (2) and the mounting substrate (20) when the varistor (1) is mounted on the substrate (20), the risk of burning the substrate (20) can be eliminated even if the varistor is in an electrically short-circuited state.
