A housing structure of a planar resistor is provided, wherein electrode extraction ends of the planar resistor are on the same side of the resistor. A housing structure body is made of an insulating material covering the surface of the resistor. An insulating structure having a groove opening facing toward or away from the resistor is provided around each electrode extraction end of the resistor. The insulating structure is configured to be a multi-tooth or multi-groove insulating structure.

An insulating sheet and a conductive terminal are provided in an electronic component, where at least one of the conductive terminals has a missing part, and where a remaining part positioned on both ends of the missing part is connected through a resistor element affixed to the insulating sheet.

A varistor module includes a base, a case, and a varistor body. The base and the case are assembled with each other to form a closed space. The varistor body includes a plurality of ceramic chips and a bridging element. The ceramic chips are disposed in the closed space. Each ceramic chip has an electrode layer on two opposite sides, respectively. The bridging element has at least two bridging segments and a crossing segment. The bridging segments are connected to electrode layers of different ones of the ceramic chips. The crossing segment is disposed between the bridging segments.

A surge arrester is provided that comprises an elongate housing, an active member, and an enclosure. The elongate housing has an interior comprising an interior surface that extends along a longitudinal axis between a first end and a second end of said housing. The active member is arranged at least partially within the interior. The enclosure is fixed to or integrally with the housing and closes the interior at the first end. The enclosure comprises a predetermined breaking line. In the event of a fault condition, e.g., a short circuit condition, the pressure within the housing increases and the predetermined breaking line allows for a defined breaking of the enclosure.
