DB Component Decoder

Features
Read full description

Lo strumento completo per studenti e appassionati di elettronica. Decoder componenti, progettazione alimentatori, database semiconduttori e quiz interattivi — tutto offline, tutto gratis, zero pubblicità. DECODER COMPONENTI Resistori: decodifica bande colore 3, 4, 5 e 6 bande. Inserisci i colori e ottieni il valore, oppure inserisci il valore e scopri i colori. Suggerimento serie E12, E24, E96. Condensatori: codici ceramici (104, 472…), tantalio ed elettrolitici. Tabella rapida dei codici più comuni. Induttori: bande colore e codici SMD (100, 4R7…). LED: calcola il resistore di caduta per qualsiasi LED. Supporta LED in serie e stringhe in parallelo, con preset per i colori più comuni. CALCOLO CIRCUITI Serie e parallelo per R, C e L, fino a 6 componenti. Costante di tempo RC e RL, frequenza di taglio, energia e potenza. Filtri RC, RL e RLC con diagramma di Bode interattivo. ALIMENTAZIONE Progettazione alimentatore AC/DC: scegli la topologia (mezza onda, ponte, presa centrale), calcola tensione DC, ripple e condensatore bulk. Verifica dropout del regolatore. Fusibili trasformatore: dimensionamento primario e secondario con margine per corrente di inrush. Scelta tra fusibile rapido, medio e lento. DATABASE SEMICONDUTTORI Decoder codici SMD per resistori, condensatori, transistor e diodi. Transistor: NPN, PNP, N-MOSFET, P-MOSFET, JFET, IGBT. Scheda completa con pinout, caratteristiche elettriche, equivalenti e sostituti. Diodi: signal, Schottky, rectifier, Zener, TVS e LED. Ogni componente con VF, VRRM, IF, package e note applicative. Regolatori: serie 78xx, 79xx, LM317, LM337 e equivalenti. Ponti raddrizzatori: database con modelli integrati e discreti. DIDATTICA Esercizi interattivi con punteggio e spiegazioni dettagliate. Cronologia degli ultimi 50 componenti analizzati. CARATTERISTICHE 100% offline — nessuna connessione richiesta. Dark mode automatica o manuale. Nessun tracciamento, nessuna pubblicità, nessun account. Progettata da un docente ITIS per studenti di Elettronica e Automazione.
