Number 3212 A Tektronix Company Application Note Avoiding Inrush Current when Testing High Series Power LEDs with Series 2260B Power Supplies Light-emitting diodes (LEDs) are quickly becoming an attractive the device is instantaneously a short circuit when a voltage is lighting source due to a variety of benefits they offer over the applied across the device's terminals. The instantaneous short traditional incandescent and fluorescent light bulbs. LEDs circuit results in an inrush current , a short duration, startup have a very long lifespan; they are highly efficient with very current that is a much greater magnitude than the LED's steady low power consumption; they do not contain mercury and are state operating current. For environmentally friendly. example, introducing an LED to an + Unlike an incandescent bulb where the lighting source is energized circuit or "hot switching" Power a filament made of a resistor that lights up when heated, an the LED will lead to dangerous Supply LED LED is a two-terminal, semiconductor device that emits visible inrush current magnitudes.
