Wondom AA-AB31521 Module Amplificateur Class D Mono TPA3118 40W 4Ω

The Wondom AA-AB31521 is a small, simple and efficient Class D mono amplifier module. It includes a TPA3118 TI chip to enable it to provide a power of 40W at 4 Ohm for an efficiency of 90%, as well as a precise sound reproduction. In addition, the module has very good heat dissipation, eliminating the need for a heat sink and ensuring long durability. The circuit is also protected by a series of overload, high temperature and reverse polarity protection.
