Precautions
Long-term Continuously ON Contacts
Using the Relay in a circuit where the Relay will be ON continuously for long periods (without switching) can lead to unstable
contacts, because the heat generated by the coil itself will affect
the insulation, causing a film to develop on the contact surfaces.
Be sure to use a fail-safe circuit design that provides protection
against contact failure or coil burnout.

Relay Handling
When washing the product after soldering the Relay to a PCB,
use a water-based solvent or alcohol-based solvent, and keep the
solvent temperature to less than 40
°C. Do not put the Relay in a
cold cleaning bath immediately after soldering.
