Advantages of toroidal transformers:
- Transformers take up less space than their traditional square counterparts, using less circuit space.
- Installing a toroidal transformer with flying leads rather than terminal blocks can save up to 60% of space.
- These transformers are easy to mount, some requiring only a single screw to secure them.
- They have flexible dimensions.
- These transformers offer significant noise reduction and emit less electromagnetic interference (EMI) than standard transformers.
- They offer a low stray field.
- They are quieter than standard transformers and create less hum.
- They offer excellent value for money: Toroidal cores consume less energy to maintain a magnetic field, and therefore use less electricity.

Très bon produit reçu en parfait état , bon emballage correspond à mes attentes. Le délai de livraison a bien été respecté.
Le transformateur est pleinement fonctionnel et ne présente aucun défaut.
Fonctionnement impeccable, j’en parle a mes copains RadioAmateurs comme moi F6EIT pour l’alimentation d’ampli lineaire sans les brouillages des alims a découpage.
