Tips

When designing the PCB, ensure adequate creepage and clearance distances around the relay contacts, especially for 250 V AC loads. Use a flyback diode across the coil to protect driving transistors from voltage spikes. For maximum contact life, consider snubber circuits for inductive loads. The relay's flux-proof design allows wave soldering, but avoid ultrasonic cleaning to prevent damage to the sealed construction.
