1) Measured on 70x70x1.5mm epoxy PCB FR4 with 52cm2 (double layer 140μm) copper
area. The load circuit shall withstand current applied until 40A ATO fuse blows.
2) The values apply to a resistive or inductive load with suitable spark suppression and at
maximum 13.5VDC for 12VDC load voltages.
3) Corresponds to a capacitive peak inrush current on initial actuation (cold filament).
4) See chapter Diagnostics of Relays in our Application Notes or consult the internet at
http://relays.te.com/appnotes/
5) Be aware of using right polarity, see Terminal Assignment. Wrong polarity will reduce
endurance.
