Les inducteurs sont des composants capables de convertir l'énergie électrique en énergie magnétique et de la stocker. Ils sont largement utilisés dans divers dispositifs électroniques, tels que les filtres, les oscillateurs, les transformateurs, etc. Ils jouent le rôle de stockage d'énergie, de filtrage, d'oscillation, etc. dans le circuit.
Les thermistances sont des capteurs dont la valeur de résistance varie en fonction de la température.En fonction des différents coefficients de température, on distingue les thermistances à coefficient de température positif (thermistance CTP, c'est-à-dire à coefficient de température positif) et les thermistances à coefficient de température négatif (thermistance NTC, c'est-à-dire à coefficient de température négatif).
