IRFZ44N Mosfet Amplifier

3 More Images

Components required -

(1.) MOSFET - IRFZ44N x1

(2.) aux cable x1

(3.) Speaker

(4.) Battery - 9V x1

(5.) Battery clipper x1

(6.) Capacitor - 16V 100uf

(7.) Resistor - 10K x1

This picture shows the output pins of this MOSFET.

Pin-1 - Gate

Pin-2 - Drain

Pin-3 - Source

Firstly we have to solder 10K resistor to Gate pin and Drain pin of the MOSFET as solder in the picture.

Next solder +ve pin of capacitor to the Gate pin of MOSFET as you can see in the picture.

Now we have to connect aux cable wire to the circuit.

Connect Left/Right (+ve) Wire of aux cable to -ve pin of capacitor and

Connect -ve (GND) wire of aux cable to Source pin of the MOSFET as you can see in the picture.

Now connect +ve wire of speaker to source pin of the MOSFET as solder in the picture.

Next connect battery clipper wire to the circuit.

Solder +ve wire of battery clipper to the Drain pin of MOSFET and

-ve pin of battery clipper to -ve wire of speaker as you can see in the picture.

Now this MOSFET amplifier circuit is ready.

HOW TO USE IT -

Connect battery to the battery clipper and plug in aux cable to mobile phone/laptop/tab..... and play songs.

NOTE : If Amplifier is not working then change the polarity of battery.

Enjoy songs with full volume.
