The SMD-1A05 is a high-performance reed relay designed for applications that require reliable switching with minimal contact resistance. This hermetically sealed relay ensures a long operational lifespan, making it ideal for environments where durability and consistency are paramount. With a nominal coil voltage of 5 VDC, it can operate efficiently within a wide range of temperatures, from -35°C to +100°C, and withstand soldering temperatures up to 260°C for a brief period.

The SMD-1A05 features a quick reset time of 0.05 milliseconds and a low capacitance across contacts (0.2 pF), allowing for rapid response and reduced signal interference. It boasts a maximum carrying current of 1 A and a max contact rating of 210 VDC, ensuring it can handle substantial loads while maintaining excellent lifetime characteristics.

This relay’s dielectric strength is rated at 1.5 kVDC between the coil and contact, and between the contact and shield, providing a robust barrier against electrical breakdown. The insulation resistance is extremely high, at 1.00E+12 ohms, further enhancing its suitability for high-reliability circuits.

With a form A (SPST) contact configuration, the SMD-1A05 can be easily integrated into various electronic assemblies, and its compact design makes it well-suited for space-constrained applications. Additionally, custom design options are available upon request, catering to specialized requirements.
