Eletrônica Aplicada
Na entrada de muitas placas eletrônicas existem componentes que parecem iguais, mas têm funções completamente diferentes. Entre os mais comuns estão varistor, capacitor supressor e termistor. 🔹 Varistor (MOV) Protege o circuito contra surtos de tensão. Quando a tensão sobe além do limite, ele conduz e absorve o pico, evitando que outros componentes sejam danificados. 🔹 Capacitor supressor (classe X ou Y) Fica ligado à rede elétrica para filtrar ruídos e interferências eletromagnéticas, evit
