As explained by Arduino to Go, each color band on the resistor corresponds to a number but this can differ depending on the band's placement. It's not complicated, but the sheer number of colors ...

These old 1N5305 current limiting diode regulators are simply constructed from a JFET with an internal feedback resistor to its gate which maintains a fixed current output.

Voltage at maximum power V mp = 17.4V Current at maximum power I mp = 0.58 A These values correspond to a standard test condition of 1000 W/m 2 of solar illumination. If the illumination reduces, the ...

A 75-Ω resistor, for instance, would restrict current through Q2 to about 10 mA. This means R2 would only have to dissipate 7.5 mW, allowing a common 1/8-W resistor to easily withstand permanent ...

Nexperia has introduced its first 5V load switch IC, which operates across 2.5 – 5.5V with 110mA to 2.5A current limiting. The 2 x 2mm NPS4053, as it will be know, is optimised use in portable devices ...
