1) Measured on 70x70x1.5mm epoxy PCB FR4 with 25cm2 (double layer 105μm)
copper area. Connecting cable cross section 6 mm2.Boundary conditions: 180°C coil
temperature;130°C solder joint. Only one relay energized.
2) The values apply to a resistive or inductive load with suitable spark suppression and at
maximum 13.5VDC for 12VDC load voltages. For a load current duration of maximum
3s for a make/break ratio of 1:10.
3) See chapter Diagnostics of Relays in our Application Notes or consult the internet at
http://relays.te.com/appnotes/
4) Measured at nominal voltage without coil suppression unit. A low resistive suppression
device in parallel to the relay coil increases the release time and reducesthe lifetime
caused by increased erosion and/or higher risk of contact tack welding.

Load limit curve I: safe shutdown, arc extinguishes during transit time.
Load limit curve II: safe shutdown, no stationary arc.
Load limit curves measured with low inductive resistors verified for 1000 switching events.
