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.
2) At 50% ON period: max. make time 15s.
3) See chapter Diagnostics of Relays in our Application Notes or consult the internet at
http://relays.te.com/appnotes/
4) 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.
