SMD/SMT Reed relæer 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

• Miniature størrelse: Disse relæer er betydeligt mindre end traditionelle gennemhullede relæer, hvilket gør dem ideelle til design med begrænset plads.
• Overflademonteringsdesign: Designed to be attached directly to the surface of a PCB, eliminating the need for through-hole drilling.
• Høj pålidelighed: Hermetically sealed contacts offer excellent reliability and long service life suitable for critical applications.
• Hurtig skiftehastighed: Capable of switching on and off very quickly (typical <0.5ms), suitable for high-frequency applications.
• Lav kontaktmodstand: Ensures efficient current flow with minimal signal loss.
• Wide Temperature Range: Suitable for various environments, from automotive to industrial control.
