Mechanical endurance
1) 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.
2) See chapter Diagnostics of Relays in our Application Notes or consult the internet at
http://relays.te.com/appnotes/
3) Measured at nominal voltage without coil suppression unit. 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
