🚨 Componentes falsos existem mesmo? Infelizmente, sim! 🚨 Mosfets, IGBTs, CIs e transistores são os mais afetados, e identificar um componente falso pode ser complicado. Muitas vezes, você só vai descobrir na prática. 💡 Dica: Evite sites como Aliexpress e opte por lojas confiáveis como Mouser, Digi-Key, ou procure componentes em assistências autorizadas e sucatas. 🔍 Já teve experiências com componentes falsos? Comente aqui! E não esquece de deixar o like e compartilhar com aquele amigo
