Automotive EMC Test SolutionsAccording to ISO 7637-2:2011 and ISO 16750-2:2012, test pulses generated by automotive transient generators need to be verified under both no-load (open circuit verification) and loaded with specified loads.
The CA ISO is a resistor box containing all load resistors required to verify micro pulse and load dump generators according to international standards and manufacturer requirements.
Highlights
One single load resistor box
Includes all required load resistor values
Highly accurate resistors (+/-1%)
High temperature stability
Resistors with very low inductance
Resistor values 0.5ohm, 1ohm, 2ohm, 4ohm, 10ohm, 20ohm and 50ohm
Benefits
Selection of load resistorsThe set of load resistors has been well selected in order to meet the wide range of source resistors specified in various national/international standards and vehicle manufacturer specifications.
The following load resistors are most used:
0.5 Ohm for Load Dump pulse as per numbers of manufacturer specifications.
1.0 Ohm for Load Dump pulse as per numbers of manufacturer specifications.
2.0 Ohm for pulse 2a and pulse 5 as per ISO 7637-2 and various manufacturer specifications.
4.0 Ohm for pulses 1, 2 and Load Dump pulse 5 as per various manufacturer specifications.
10.0 Ohm for pulses 1 and 2 as per ISO 7637-2 and various manufacturer specifications.
20.0 Ohm for pulse 1 as per ISO 7637-2 and various manufacturer specifications.
All load resistors are non-inductive and have a tolerance better than 1% as per standard requirements. They show sufficient power dissipation for the transient pulse energy.
