1) Measured on 70x70x1.5mm epoxy PCB FR4 with 35cm
2
(double layer 105µm) copper
area. Cable cross section 6mm². Boundary conditions: 180°C coil temperature; 130°C
solder joint. Solder joint results above 130°C on request. The load circuit shall withstand
current applied on 40A MAXI fuse.
2) The values apply to a resistive or inductive load with suitable spark suppression and at
maximum 13.5VDC load voltages.
3) For a load current duration of maximum 3s for a make/break ratio of 1:10.
4) See chapter Diagnostics of Relays in our Application Notes or consult the internet at

5) For unsuppressed relay coil. A low resistive suppression device in parallel to the relay
coil increases the release time and reduces the lifetime caused by increased erosion
and/or higher risk of contact tack welding.
