This Is a 5.0 Volt 0.7 AMP Samsung phone charger

Step 1: Tools

These are the tools I used If you take one apart you may need to use different tools:

Wire Cutters

Pliers

Flat Screwdiver

Step 2: The Parts

2 Resistors

2 400V 4.7 Micro-Farads Electrolytic Capacitor

50V 470Micro-Farads Electrolytic Capacitor

Useless connector (for me)

And a useless transformer because I couldn't find the datasheet so I don't know what it does.

I had a couple a problems with the capacitors so I'm not really happy of this overall, but, hopefully I'll do more of these "Whats Inside" Instructables which will be better.

Does anyone know if the is voltage converted from AC to DC with the capacitors? I am asking this because there is no bridge rectifier (diode bridge).

Do you like taking apart electronic devices? I've made a collection of a couple"What's Insides" If you're interested:

<p>i think the transformer outputs te specified voltage (5V) and the Caps just do the &quot;buffering&quot;/filtering job.</p><p>Maybe theres' a couple diodes under the transformer to make the AC-DC conversion.</p>
<p>I am a Little confused - You say 2 Resistors and 4 Capacitors only which look to be Electrolytic's (Polarity Conscious).</p><p>You do not say what E10 JH1415 is, which I am assuming is the Transformer. It would be bad design, and I have never heard of the use of electrolytic capacitors to rectify a.c. and all the components look correct for a charger unit. There has to be a d.c. source feeding the Capacitors whether it be a simple diode or a bridge rectifier. I suspect on closer examination of E10 JH1415 you will find your answer. another solution would be to redraw the circuit from the PCB tracks to gain an idea how it is wired</p>
<p>I already threw the transformer a couple days ago into the trash so I can't do that, And yes, I'm also confused</p>
The transformer very well could have a built in converter. I've seen a few like this but have never taken one apart to see exactly how it's accomplished.
<p>That could be true, Next time I take one of these apart I'll open the transformer and check</p>
