This can result in your iPhone's speakers sounding distorted and muffled, whether for media playback or during phone calls. We're taking a look at the "do's" and "don'ts" of how to get your iPhone ...
However voltage spikes can also have more mundane causes such as a fault in a transformer or higher-voltage (primary circuit) power wires falling onto lower-voltage (secondary circuit) power wires as a result of accident or storm damage. Voltage spikes may be longitudinal (common) mode or metallic (normal or differential) mode.
Inrush current, input surge current, or switch-on surge is the maximal instantaneous input current drawn by an electrical device when first turned on. Alternating-current electric motors and transformers may draw several times their normal full-load current when first energized, for a few cycles of the input waveform.
There were also reports of device instability from some users on iPhone 6 and iPhone 6S models, including situations where the device would unexpectedly shut down once its battery capacity reached 30% (with one user having described the battery percentage as unexpectedly jumping down to 1% before doing so, but still appearing as 30% after the ...
TVS diode as array. A transient-voltage-suppression diode may be either unidirectional or bidirectional. A unidirectional device operates as a rectifier in the forward direction like any other avalanche diode, but is made and tested to handle very large peak currents.
Surge Protection Device (SPD) for installation in a low-voltage distribution board. A surge protector (or spike suppressor, surge suppressor, surge diverter, [1] surge protection device (SPD), transient voltage suppressor (TVS) or transient voltage surge suppressor (TVSS)) is an appliance or device intended to protect electrical devices in alternating current (AC) circuits from voltage spikes ...
