Circuit protection

solutions from

the technology leader

Today's automobiles includemore electronic systemsthan ever before. Over theirlifetime these systems areexposed to a wide range ofpotential overcurrent andtransient voltage hazards.Overheating of actuators,traces and wire harnessesplus transients caused byload dump, mutual coupling,ignition pulse, ESD, noise…these are just a few of theissues system designersmust contend with.

More Applications.

Innovations in safety andenvironmental systems,as well as driver expectationsof greater comfort,convenience and securityare all driving the trendtoward more sophisticatedon-board electronicapplications. Many of thesesystems are critical tovehicle performance andpassenger safety andrequire robust protectionagainst electrical threats.

Evolving Technologies.

The new 42V PowerNetposes new circuit protectionchallenges as the demandfor more electrical power invehicles increases beyondthe capacity of today’sconventional 14V systems.Gas/electric hybridsand emerging fuel celltechnologies are alsocompletely changing therequirements for wiringand power distributionprotection solutions.

Reduced Cost.

The need to reduce vehiclecost and strict space andweight requirements havealso helped drive theevolution toward electroniccontrol of traditionalmechanical loads.

Continued Reliability.

Even in the face ofincreased complexity andvulnerability, automobilesmust continue to meetconsumer expectations forreliability.
