| Those funny looking 'Resistor' shaped Inductors!! |
| (1/1) |
| GlennSprigg:
Most people may have seen/used them. My rapidly dwindling EyeSight (and Brainpower!) causes me many problems now! I'm talking about the little buggers that 'look' like 1/4 W Resistors, except their outer body is sort of a greenish/aqua colour!! There are 4 colour band & 3 colour band versions. (Australia uses 'Colour' not 'Color' xox). The 4-colour bands have the same colour order as resistors. Bands 1 & 2 indicate uH, with band 3 being the multiplier. The 4th band is a unique system of accuracy/tolerance. The 3 band devices do NOT show a Multiplier, and the 3rd band is just an 'accuracy'. When I'm playing with certain circuit designs/tests, I have/use quite a lot of special Boards to plug into a circuit. (And YES, (joking!), I have SPECIAL leads that introduce NO Capacitance/Inductance/Resistance into the circuit! haha..). Small decade resistance boxes, Electrolytic & general capacitors, and Inductors, to substitute in circuits, like the following photo of a gang of Inductors from 1 to 1000 uH... Obviously, an Inductor must comprise of a series of windings, and I thought it was interesting when I found a YouTube video where someone had broken one apart!! to show the fine windings inside. The English & Dialog is bad, but it is what it is!! 8) Interesting note, that he keeps talking about a LEAD Inductor, (like Lead the Metal), but he should be pronouncing it LEED, because these Inductors have Leads (Leeds) attached, like resistors!! |
