Introduction aux relais Reed CMS/SMT

Understanding the advantages of Surface Mount Technology in modern switching applications.

Relais Reed CMS/SMT are a type of electronic component that utilizes a magnetic field to control the flow of electrical current. They are designed specifically for Surface Mount Technology (SMT) assembly, offering a compact and efficient solution for automated manufacturing.

Key Features

  • Taille miniature : Ces relais sont nettement plus petits que les relais traversants traditionnels, ce qui les rend idéaux pour les conceptions à espace restreint.
  • Conception de montage en surface : Designed to be attached directly to the surface of a PCB, eliminating the need for through-hole drilling.
  • Haute fiabilité : Hermetically sealed contacts offer excellent reliability and long service life suitable for critical applications.
  • Vitesse de commutation rapide : Capable of switching on and off very quickly (typical <0.5ms), suitable for high-frequency applications.
  • Faible résistance de contact : Ensures efficient current flow with minimal signal loss.
  • Wide Temperature Range: Suitable for various environments, from automotive to industrial control.
