摘要:
A varistor component with improved failure safety is provided. The varistor component comprises a varistor and a second external contact. A current path between the varistor and a second external contact can be actively blocked by a shutter if the temperature of a heat-sensitive element exceeds a critical temperature.
摘要:
A surge suppression system provides surge protection both locally within the radio station building were the power plant and telecommunication equipment are located and remotely next to the radios and antennas located outside of the building on the communication tower. An external surge suppression unit provides a waterproof enclosure for both surge suppression devices and fiber optic connectors. A rack mountable surge suppression unit provides local in-line surge suppression protection for the electrical equipment located in the communication station. A unique surge suppression tray is hot swappable so that multiple surge suppression devices can be replaced at the same time without disrupting radio operation. Pluggable surge suppression modules can be used in both the external surge suppression unit and the rack mountable surge suppression unit.
摘要:
An improved overvoltage protection component is provided. The overvoltage protection component has a first internal electrode contained within a dielectric material. The first internal electrode is electrically connected to a first termination and a second internal electrode contained within the ceramic dielectric material is electrically connected to a second termination.

A coaxial in-line assembly comprising a body (5) with a bore (7) therethrough, an inner conductor (15) within the bore (7) extending between a first connection interface (9) and a second connection interface (11), an inner conductor capacitor (31) within the bore (7) coupled between a surge portion (17) of the inner conductor (15) and a protected portion (19) of the inner conductor (15), an inner conductor cavity (33), the inner conductor cavity (33) closed between the surge end (27) of the inner conductor (15) and the protected end (29) of the inner conductor (15) and an electrical component electrically coupled in series with the surge end (27) of the inner conductor (15) and the protected end (29) of the inner conductor (15), enclosed within the inner conductor cavity (33).
摘要:
A surge protection circuit and a connector and an electronic apparatus using the circuit are provided. The connector includes a plurality of metal lines (301-308), a plurality of resistors (311-314), a ground metal (201), and a capacitor (300). Each metal line has a pointed end. There is a distance between the pointed end of the metal lines and a pointed end of the first end of each resistor corresponding to the metal line. The capacitor is coupled between the ground metal and second end of the resistors. Thus the surge endurance of product can be increased by the invention, and the damage to the internal components of product can be prevented.
摘要:
A method of making a transient voltage protection device includes forming conductive lines (12, 14) on a substrate (10) where the lines form conductive paths between electronic components. A gap of 3 mils or less is formed in at least one of the lines by cutting the line with a saw or a laser. The gap is covered or filled with a neat unfilled polymer, glass or ceramic (22) to prevent contamination of the air space in the gap.
